Workgroup: Fetching privgroup of a private workgroup returns 200

[akkornel]

If a certificate without permissions attempts to fetch the privgroup of a private workgroup (a workgroup where the certificate is not an administrator), the following is returned:

{
  "members": [],
  "name": "test:1",
  "message": "This is a private workgroup!",
  "administrators": []
}

Problem is, the return code is 200. I expected something like 401 to be returned instead.

I'm not sure if this is intentional, so I've opened RITM00653617 to find out.
