Is there vertical plane detection support for UE 4.21/4.22 for ios - ARkit?

I know that ARcore 1.7 sdk for UE (from github) supports vertical plane detection but what about AR kit? Handheld AR template does not show vertical planes (in config data Vertical plane is ticked). did anyone successfully detect vertical plane and used it?

My end goal is corner detection ! i wanted to find the intersection point between horizontal and vertical plane,
