Make sure there is a humid hide in there now rather than after it goes wrong. A hide with damp sphagnum moss or damp paper towel, substrate dry everywhere else, and something rough she can rub against to get it started.
A good shed comes off in one piece, inside out like a sock, eye caps included. When you find it, check it for the eye caps specifically, because that is the bit that gets retained and you want to know before the next cycle rather than after.
