Room Multiplayer System

Hi! I’m new to Gdevelop, and I have a problem that I cannot solve. I’m making chess with different pieces and behaviors, but that isn’t the problem. I want to implement a room system, in which a user can create a room, maybe also create a password though I don’t know how and the second player can join the room from the list and enter the password (I picture it like Among Us).

If anyone knows how to make this system (and maybe the password) work, let me know. Excuse me for my poor English since it’s not my native language.

Best regards.

check these out, but I wouldn’t recomend adding multiplayer since you’re new to the engine.
It’s not that easy.
