First, you need a lifecycle and a relay wired and set the settings to game start and random player. If you want, you can also throw in a notification so they’re aware.
If you want the player to be random, you could have a game overlay (button) that when pressed, relay thing, and set player to configured team (spectators)
Well, our mods gotta be rich right? To make them rich, you could have a button that gives a lot of in-game currency using game overlay and item granter.
