Actor look on player after On See Pawn

Hi, I wanted to make actor look on character after seeing him. I was planning to use it with FocusOn function, but don’t know how to make it work with On See Pawn function. Do you have any idea how can i make it?

Ok, I created a box collision, and used it as triggerbox, so when character enters triggerbox, the actor looks toward character, until it leaves the triggerbox.
