| None                       | Joinability not set or no lobby exists yet.                                                                                                                                     |
| JoinableByFriends          | Default value. The lobby is joinable by users who are followed by an existing member of the session.                                                                            |
| InviteOnly                 | The lobby is joinable only via an invite.                                                                                                                                       |
| DisableWhileGameInProgress | This option will close the lobby only when a game is in progress. All other times, it will keep the lobby open for InviteOnly so invitees can join when no game is in progress. |
| Closed                     | This option will close the lobby immediately.                                                                                                                                   |
