How can I make a multiplayer game for Quest 2 like Onward?

Hey everyone, As the “title” states, I wanted to ask if anyone knew how I could implement multiplayer in my Quest 2 Game (Virtual Reality). I would like it to look like the game Onward on the quest: you can see all available servers and then choose which one to join. If anyone could help that would be greatly appreciated (if anyone knows a good YT vid etc.) Thanks, Matteo
