Tutorial for photon server who host the map?

Hello, I'm making a multiplayer game with Photon Network (because i've find some tutorials on it and peoples were saying it's easier with photon...), and I want my server to host the map, not the master client (my game is a Rust/DayZ/Minecraft/... like, so a simple server is bad for that). I'm looking for a tutorial to learn how to make a server who host player/map?

Cordially.
