how to get overlappig actor in the Player Controller?

Hey guyzz. Here is what a i want . I got main character and a few types of controllable mirrors(pawns), and i want to posses between chacrater and pawn , once the character overlaps box collision of pawn , and presses “E” keyboard. But the problem is ,in the “PLayer Contoller” blueprint where all possesion goes , how to know which exactly BP the charcater is overlapping ,or is it even overlapping something ? cuz there is no overlap evnets in the Player controller . A bit stuck , hope you understand what i really a want

Do the possession in the pawn. If you do it in the controller, you have to look at all the pawns to find out which one to possess.

There are no rules about doing possession in the controller.
