How to synchronize an object spawn and detect which player taps on it first?

Hi, I have been learning unity and I wanted to try learning to make multiplayer games using Photon. I wanted to start off with a simple game where I spawn a ball at the same time for 2 players and the first player to click the ball on their screen wins and the loser is displayed with something like "The other player clicked the ball first". How would I go about this on Photon? I have already integrated the asset but I don't know where to go from there, most photon tutorials show FPS games or games where the players are in the same screen which is not what I'm aiming for. Any help would be appreciated, thank you so much.
