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.
