Couple of things I've noticed:

Should disinvite dismiss not accepted notifications with invite?

For accepted users, disinvite just removes them from the room on remote server. Could we send a notification as well (admin has unshared a room with you) to handle it on the frontend and leave the federated room on local server?

It should, fixing this now

We should not send a (push) notification, but we should trigger a signaling message for the user I guess?

Tested. Something weird was on my local dev, but now it works fine. Removing of participant from both rooms is processed correctly
