Looking to give a structure the ability to emit health regeneration - Ark Dev Kit / UE 5.2

I have a structure that I am wanting top emit health regen when the pawn/player gets within the box collision area to start regenerating health. Being in the ARK ASA “Ascended” Dev Kit, it uses UE 5.2.

I have my box collision setup but the guide I was following was UE4 so a bit out dated.

Any help is greatly appreciated.
