Change camera on blueprint's mesh collision

I want to change to a top down camera(which is either a BP or an actor in the level, which ever one works best) when the player collides with a certain BP’s mesh, but it won’t let me use my already defined camera.
And I don’t know exactly where to implement such a BP, I was trying in the mesh’s BP where I use the EventBeginCollision.

Any help would be appreciated, thx.
