Swift arkit detect hand and nails, and overlay object on nails?

Question

iOS

I would like to know how to detect a person's hand and nails, and then use arkit to put an object on the nails. Frankly speaking, I have been looking for information on this subject in Google for several days, but I have not found anything sensible. I would be very grateful for your help! Thank you!
