## Improvements
- This PR calls `fitView` when the Reactflow component inits. It tries
to fit the flow in a view with a fixed min and max zoom.
- Every time the WorkflowDiagramCanvas is rendered for a different
`workflowVersionId`, the `fitView` will be re-called. This is
implemented with a React `key`.
- The canvas will be re-rendered when an activated/deactivated version
is updated (and a new draft version is created.)
- It will also be re-rendered when the user selects another workflow
version and this doesn't cause the `WorkflowDiagramCanvas` component to
unmount. It happens if the user wants to go the previous or next
workflow or workflow version.

## Notes
Closes#7047
This PR is a simplification of #7151. We'll have to improve the way we
manage zoom in another PR.
## Setup
This PR can be tested only if some feature flags have specific values:
- `IsWorkflowEnabled` equals `true`
- `IsQueryRunnerTwentyORMEnabled` equals `false`
These feature flags weren't committed to don't break other branches.
## What this PR brings
- Display buttons to activate and deactivate a workflow version and a
button to discard the current draft version. I also scaffolded a "Test"
button, which doesn't do anything for now.
- Wired the activate, deactivate and discard draft buttons to the
backend.
- Made it possible to "edit" active and deactivated versions by
automatically creating a new draft version when the user tries to edit
the version.
- Hide the "Discard Draft", button if the current version is not a draft
or is the first version ever created.
- On the backend, don't consider discarded drafts when checking if a new
draft version can be created.
- On the backend, disallow deleting the first created workflow version.
Otherwise, we will end up with a blank canvas in the front end, and it
will be impossible to recover from it.
- On the backend, disallow running deactivation steps if the workflow
version is not currently active. Previously, we were throwing, which is
unnecessary as it's a valid case.
## Spotted bugs that we must dive into

- Create a workflow version when the user visits an empty workflow.
- If the trigger is not defined yet and the user selects either the
standard object type or the event type first, we automatically select
the first option of the other value. Indeed, every state update is
automatically saved on the backend and we need both standard object and
event types to save the event name.
- Introduces a change in the backend. I removed the assertions that
throw when a workflow version is not complete, that is, when it doesn't
have a defined trigger, which is the case when scaffolding a new
workflow with a first empty workflow version.
- We should keep validating the workflow versions, at least when we
publish them. That should be done in a second step.
- Removed the route I previously used to visualize workflows
- Created another tab in the `<ShowPageRightContainer />` component in
which we display the visualizer
Questions:
- Should I use a feature flag to hide the feature?
Closes#6858
- Improve the design of the right drawer
- Allow to update the trigger of the workflow: the object and the event
listened to
- Allow to update the selected serverless function that a code action
should execute
- Change how we determine which workflow version to display in the
visualizer. We fetch the selected workflow's data, including whether it
has a draft or a published version. If the workflow has a draft version,
it gets displayed; otherwise, we display the last published version.
- I used the type `WorkflowWithCurrentVersion` to forward the currently
edited workflow with its _current_ version embedded across the app.
- I created single-responsibility hooks like
`useFindWorkflowWithCurrentVersion`, `useFindShowPageWorkflow`,
`useUpdateWorkflowVersionTrigger` or `useUpdateWorkflowVersionStep`.
- I updated the types for workflow related objects, like `Workflow` and
`WorkflowVersion`. See
`packages/twenty-front/src/modules/workflow/types/Workflow.ts`.
- This introduced the possibility to have `null` values for triggers and
steps. I made the according changes in the codebase and in the tests.
- I created a utility function to extract both parts of object-event
format (`company.created`):
`packages/twenty-front/src/modules/workflow/utils/splitWorkflowTriggerEventName.ts`
This PR adds the possibility of creating new steps. For now, only
actions are available. The steps are stored on the server, and the
visualizer is reloaded to include them.
Selecting a step opens the right drawer and shows its details. For now,
it's only the id of the step, but in the future, it will be the
parameters of the step.
In the future we'll want to let users add steps at any point in the
diagram. As a consequence, it's crucial to be able to walk in the tree
that make the steps to find the correct place where to put the new step.
I wrote a function that returns where the new step should be inserted.
This function will become recursive once we get branching implemented.
Things to mention:
- Reactflow needs every node and edge to have a unique identifier. In
this PR, I chose to use steps' id as nodes' id. That way, it's easy to
move from a node to a step, which helps make operations on a step
without resolving the step's id from the node's id.
## Features
- Fetch a workflow and display it in a tree with the React Flow library
- The nodes are positioned by an algorithm
- The feature is put behind a feature flag. The `/workflow/:id` route is
disabled if the flag is off.
- I started implementing a right drawer. That's a big WIP and it will be
finished in another PR.
## How to test this feature
1. Create a workflow instance in the database through a GraphQL query.
See below for instructions.
2. After enabling the feature flag, you should be able to see the
workflow you created in the workflows list. To visualize the workflow,
go to the `/workflow/:id` page where the id is the id of the workflow.
See the video for a quick way to do so.
```gql
// First
mutation createWorkflow($data: WorkflowCreateInput!) {
createWorkflow(data: $data) {
id
}
}
// Result
{
"data": {
"name": "test"
}
}
// Second
mutation createWorkflowVersion($data: WorkflowVersionCreateInput!) {
createWorkflowVersion (data: $data) {
id
}
}
// Result

"name": "v1",
