What is "ReverseDirectorystore.Shadow 3" that I found on the desktop of my MacBook Air (2017) running maOS Monterey?

I was recently scanning through my MacBook Air 13 (2017) running macOS Monterey when I noticed a few programs installed on my desktop that I'd never seen before. One was particularly troubling just based on the nefarious-sounding name of ReverseDirectorystore.Shadow 3. I don't recall installing this program along with quite a few others. My Apple ID is also used on a MacBook I gave to my girlfriend so she has access to my Apple ID but I am not sure if she can/would upload programs to my laptop. Can anyone please shed some light on this situation?
