How to use collision query

This is one of those questions that are so simple I can’t even find out the answer. Anyway, I am using a punch, and when the character is punching, I set collision of two collision spheres connected to his hands to query only. Now, I was wondering how to use the query. If there is an event, I can’t find it. Please let me know.
Thanks

You need to implement the Begin Overlap event for your fist-shapes. Of course, you also need to make sure that collision profile settings will trigger an event for whatever pair of shapes you want the event to trigger.

Can you give me an example of that?

Ok figured it out, what I did was set an anim notify and then got actors that the fists were overlapping, damaging them if the component was overlapping at least one Aicharacter.
