Spawned Actor communicate with Level Blueprint?

Hi, I’m having trouble getting an actor that I spawn to fire an event into the level blueprint.

What I want to have happen is this.
A gun pickup is spawned and when the player walks over it, an event is fired into the level blueprint.

Currently my set up is this.
There is a “G” button event that will spawn a gun_pickup blueprint. The gun_pick up blueprint has an “On Actor Begin Overlap” Event which calls an event dispatcher. How do I link this event dispatcher in the level blueprint?

Any help would be greatly appreciated.
