That's as maybe, but it belongs NOWHERE near an air fryer😕. (Read your earlier post)😜.

If you can tell me why this is bad, you'll have my attention, this is air fry finish
Because it was the best steak I ever had

I'm somewhat of a traditionalist. Seasoned (As yours was) coat the meat, not the pan with an oil of your choice. Pan fry as required for internal pinkness, rest and serve. I'm not saying it wasn't lovely, it probably was. I'd just never put my steak in a air fryer. Personal preference🫂.
Don't you have to finish really thick cuts in the oven?
