I need to verify that users listed in a field are 'assignable users' in specific projects. This verification needs to be done routinely and continuously, hence the need to do this via REST API from a script.
I am able to get all the userIDs listed in said field, I now need to check that they pass the assignable user permission test.
I know how to get a project's permission scheme using the REST API and thus I can get the permissions and 'holders', which gives me the projectRole values. But for the world of me, I don't seem to be able to get the 'actors' (I guess that is the term) for a specific project - I only get default actors, if they have been set.
