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)
Filthy Rich
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.
