Offered Sessions
The Offered Sessions list is available in X Manager for Domains. Shared sessions are available if an owner of a running session adds you to the Allowed Users list for the session.
Joined Sessions
The Joined Sessions list is available in the standalone X Manager. This list is empty until you join a session. To join session, you need a connection URL sent to you by the owner of the running session.
NOTE:If you don't use session sharing, you can hide the Offered Sessions or Joined Sessions item from view using the Preferences Dialog Box.
