Not sure who the target audience for this is?

ActivityPub (Mastodon etc) has already very granular permissions wrt. who to federate with, which posts to make public, edit or withdraw posts after initial creation, etc. catering to EU privacy and moral/personality rights demands.

For closed group chat, there are many alternatives.

Discord is after all a video chat app designed to be used during a gaming session first and foremost.

See, for you it's that, for me it's strictly text app with good notifications and messages delivery, convenient group management, etc.

If i wanted video chat app I'd to for twitch.
