AI character cannot sit to chair

unreal engine 4.27

now, the situation is as follows

I’m trying to get the AI to randomly walk around and sit in a chair if AI overlap the chair.

my Behavior Trees is this

Moving around randomly is working well.
I want AI to move to the sphere and change to arrow orientation when AI overlaps the chair, but it doesn’t work!

my BP_Chair is this.


my BP_AI is this

I’ve done a lot of research, but I’m having a hard time finding a way to do this without using Behavior Trees…
please help me!!!
