Blueprint, trying to make a trigger for a light

When trying to find an option “OnActorOverlapBegin” I dont have it in a blueprint section.
P.S. When Im selecting the trigger, I don’t have special options in the blueprint section.


OnActorOverlapBegin is not an option. It is an Event.
If you right click on a object, you can see this

After selecting OnActorBeginOverlap, you get event node in Level Blueprint.
