This is the Prefab of the player to be created in the LobbyScene.
This Prefab must have a NetworkLobbyPlayer component on it.
In the lobby Scene, this will be the active player object, but in other Scenes while the game is running, this will be replaced by a player object created from the GamePlayerPrefab. But once returned to the lobby Scene this will again become the active player object.
This can be used to store user data that persists for the lifetime of the session, such as color choices or weapon choices.
