So I've found the problem.
on an online server of "mongodb-server" was installed.
when I changed it into "mongodb-org-server" He has shown the groups.
So it could be because it is located on the MongoDB.
I would like that new posts from normal members need approval first, but posts from the "staff members" should pass through. I think the post queue currently applies to all users. It would be great if we can set that for each user group instead.
Makes sense. Please open an issue on our github.
