How do I make an AIController control only a pawn at once?

Hello guys, I’m making a singleplayer board game in which you play against 5 AIPlayers. My question is, how can i manage to implement the change of turn between the AI Players? Example: It was AIPlayer 1 turn and now i want to pass it to AIPlayer 2. Any help is welcome.

You need to tie it with you turn system, keep the track which controller has a turn and when they passing, unposses pawn of controller with last turn and posses next controller. Also make a map for tracking which pawn belong to which controller.
