Questions about online games with P2P

I want to create an online game and I saw that GDevelop has a tool called P2P, but I didn’t quite understand how it works. I wanted to create a game where you build a kingdom and fight other players to conquer villages, farms and tthis kind of stuff, but I don’t know if the information about the player who disconnected would still be in the game. I also wanted to host the server on only one machine and I didn’t understand if this is possible. Can anyone tell me how this tool works?

If you don’t like our wiki, I believe you’ll find some video tutorials on YouTube, to help you understand the basics.

Yeah I have NO idea how this works either if someone could explain that would be nice.
