On JSM, when a participant has access to a request (added as a Request Participant) but not to the Request Type, Jira blocks all requests to the backend causing Forge apps to not load at all and giving the following error:

403 error The user does not have the correct application access required for this resource

Steps to reproduce:

1. Ensure that Restrictions are enabled for a specific Request Type.
2. Add User X and Forge App User to the Restrictions for that Request Type.
3. Add a user who is not included in the Restrictions (User Y) to the ticket so they have access to the request. (Request Participant)
4. User Y can interact with the ticket, but for some reason, the Actions panel does not appear for them.
