Restrict room creation

Is it possible to restrict room creation so, that only “admin” group users can create rooms but all others cant?

I currently have a “lobby” room - a generic Jitsi room instance. I wan’t everybody to be able to join this room always. But when the user is in lobby room, I want them to be able to join another room after admin group user has created it. And when we have transferred to another room, people should be able to return back to the lobby room and possibly transfer to another room again when admin has generated it.

So basically non admin users should be able to move between the “lobby” room and admin generated dynamic rooms.

Is there any authentication methods that I could use to achieve this?

Did you check secure-domain and breakout rooms?
