How to make game "restart" at end of game?

Currently, my game ends after round 3 and just sits on the game scoreboard screen with “play again” and “return to lobby” buttons.

What I want, is for it to continue past the scoreboard screen, and spawn the players on the island start pregame spawn pads, to restart the game.

I have auto start on, post game type classic, the spawn pads set as island start pads, and island settings device setting the rounds to 3 and round timer to 7 min.

How do I do what I need here?
