If you're really having problems with the door being on top of the cage you could just try putting a tube, ball or box, anything she will happily climb into, wait for her to climb in then gently lift her out & carry her to a playpen, bath or other safe place, even a large plastic storage box (with a few toys to explore) & try interacting there.
Top doors are a bit of a pain as it's only natural for them to be scared by hands coming from above, as she seems comfortable with you around the cage you might do better trying this way.
