How to Trigger an Event with Capsule Component(Player Start)?

I am trying to trigger an event with the camera. First of all, I am not sure if it’s even called camera technically, but I am talking about the “player start” component in the world outliner. I’ve tried "cast to capsulecomponent and a few others and it doesn’t seem to be working. When I change the event trigger option to “Event BeginPlay”, it works perfectly. But my goal is to trigger an even when the camera gets close to an object, rather than when I hit the play button.

Any thoughts on what I am doing wrong?
