How do I make it so that when the player walks through box trigger the wall disappears

Sorry, I’m very new to UE, but I am using the FPS template and have a box trigger placed. I am trying to make it so that when the player goes through the trigger wall1 will be destroyed. I currently have OnInputTouchBegin (TriggerBox) and set it to execute DestroyActor, but I can’t change the Target from self. I know that this is probably completely wrong, but any help is appreciated. Thank you!

place a trigger box in the level where you want. then select that then right click on that then select add events then select onActorbeginoverlap then

Thank you so much!
