Reentering a room after disconnect

I noticed that if I’‘m in a room and I exit my client, then restart and enter the same room I don’‘t get an answer to my presence message, I guess since I’'m still considered an occupant. Is there a standard way of handling this situation?

smae situation here and looking for solution.
