Google Play Games- Realtime Multiplayer: Character Obtaining/Creating

Hello over there. I'm trying to make a multiplayer game with Google Play Services, but i stuck at some point. All of my configurations are OK. I Sign in with the 2 device, create room and another one is joining. It loads another scene. Also with hr SendMessageToAll and OnRealTimeMessageReceived functions, i'm broadcasting the local player's position to other one (to ui text). But somehow, i didn't get the algorithm of how can i make a 2 player, which controls depends to each of them. In the game screen, i'm writing this user's name to text mesh, and as i said; broadcasting local position's to another one by text. But i don't exactly know how can i instantiate 2 player. If any scrreenshot is needed, i can add. Please give me some solution...
