XMPP MUC - Automatically join to room after added membership by another user

Question

When I open my application, user gets MUC JIDs to be joined and then user can see if there are any new messagesm, he can open room etc. Is it possible to add new MUC in realtime to the availabe rooms when other user will give the membership?

Scenario:

• user1 logs in, rooms are displayed.
• user2 grants membershipt to user1 to room1 that user1 was not there
• user1's list is refreshed with the new room - room1

Thanks, Michal
