Mirrored Medicine Cabinet

I have a mirrored medicine cabinet that you have to touch to open, which is very annoying because it leaves a fingerprint. Do you have a suggestion for a knob or something that can be put on it? It would have to be mounted on the lower right corner
I've attached a couple of pictures of the latch, tho it's hard to take pictures of mirrors.
Let me know what you think.
Thanks so much!
