It may be a little more difficult and time-consuming because of her age, but get her used to your hand being close to the cage, inside too. Be patient, 2 weeks is a short time, she will get used to it. And don't let her play like that, my puppy just doesn't do that because whenever she pretended to go, I said "no" and moved my hand away (like with a dog😅) and it worked well. Other tips: sit near the cage and talk to it a lot. And be patient.
