SECURE Domain & Lobby

I am trying to achieve the Lobby room while using secure domain.

I have installed jitsi with no problem, the lobby function was there, too.

But I want to limit, so rooms can be created only by hosts, and guests can join after the host admits, or just kicks them out.

After achieving the first part(only hosts can create a room) lobby function was disappeared from the security section.

Please, can someone help me? I would be very thankful.

The example I have followed:
