gameProperties property
A set of custom properties for a game session, formatted as key-value pairs.
These properties are passed to a game server process in the
GameSession object with a request to start a new game session (see Start
a Game Session). This information is added to the new GameSession
object that is created for a successful match. This parameter is not used
when FlexMatchMode is set to STANDALONE.
