## Context
We recently introduced a change that now throws a 401 if the token is
invalid or expired.
The first implementation is using an allow list and 'IntrospectionQuery'
was missing so the playground was broken.
The check has been updated and we now only check the excludedOperations
list if a token is not present. This is because some operations can be
both used as loggedIn and loggedOut so we want to validate the token for
those sometimes (and set the workspace, user, cache version, etc). Still
not a very clean solution imho.
