4 Qs re Using Jitsi for AA-type Weekly, Public Meetings

I would very much like to help communities currently meeting online using Zoom— such as AA— have access to jitsi’s wonderful FOSS platform.
However, certain types of online meetings open to the public (like AA) need (alas) to have tighter moderation controls.
I think I understand from reading Jitsi Meet Security & Privacy | Is Jitsi Secure? that moderation controls re kick-out and mute can be set up for jitsi meetings when a meeting instance is installed to a host server.
I can’t find info telling me whether meetings created through a jitsi installation can

  1.     limit/share who can start/end meetings (create "co-hosts" once meeting has started, to share moderation duties)
  2.     limit who can share screens
  3.     limit who can communicate with whom via chat

The other crucial question for online, scheduled meetings open to the public (such as AA) is to create a permanent secure link/passcode. It’s not practical to post new links each week for every meeting on a find-a-meeting site. A public meeting needs to be able to post its permanent link to a website.

4, Is there any reason why an installed jitsi meeting instance (which can only be opened/started by a credentialed host) shouldn’t post a permanent link? That is, does posting such a link make the meeting/server vulnerable to hackers? (Beyond bombing and trolling; I mean hacking into moderation/start-end privileges or into the server install.)

Please forgive the ignorance expressed in some of these questions. I appreciate your time and patience in answering them.

On a self-hosted instance, no. The public instance is set that way because there’s no user-data permanence. However, if you host your own server, you can choose to re-use the same link/room, you would just want to make sure you change the password each time so you reduce the likelihood of unintended guests.

Thanks! I appreciate the clarification.

But the deal with a publicly available meeting like an AA or other weekly, announced meeting is that it can’t have a new password every week.

If the mission is to be there for desperate strangers who might need to attend their first meeting, there’s no way to get the password to that stranger. So the meeting has to have a permanent link/room, and then there has to be a host monitoring the “lobby” and watching over interactions to make sure no one is behaving inappropriately.
