Question: Blueprints. Add force to other actor (from Event begin overlap)

There are characters and pawns that need to bounce off the trampoline. (and they have different collision meshes) How do I get the begin overlap to interact different types of objects? I have a pawn. I have a character. In blueprints I can only tell it capsule colliders. I would like to be able to apply some kind of general rigidbody physics ruleset via blueprints. But at the moment it wants me to know beforehand what the object type is.
