How to detect if my pawn is near a wall(for wall jumping animation)

So I have this wall jumping mechanic, and now I want to give the player a flipbook when he is standing near the wall. I can’t manage to find how to do this, only how to do it WHEN they jump from the wall. I need help, here are my blueprints for the wall jumping.

The wall is a TileMap.
Also if you could tell me how to make my player fall down slowly when he is near the wall, like is he holding to it that would be great, thanks!
