-- Updates game session properties. This includes the session name, maximum player count, protection policy, which controls whether or not an active game session can be terminated during a scale-down event, and the player session creation policy, which controls whether or not new players can join the session. To update a game session, specify the game session ID and the values you want to change. If successful, an updated 'GameSession' object is returned.
