How do i make an object visible only to the person who created the room?

I am currently trying to make sort of a waiting room where players wait for other players to join. But after 2 or more than 2 players joined the room, i enabled the start button which just starts the game by switching to the game scene and the problem is that the start button is showing to all the players. I just want it to show it to the person who created the room and not the other players. Btw im new to photon. Please help me😐️
