Number Pad not working in Remote Connection on Ubuntu

When using my laptop which is running Ubuntu 21.04 and connecting to a Windows computer in the office, the number pad stops working. I am using the Chrome app / browser connection option, not the Beta Splashtop business app, since it wont install on 21.04.

The number pad functions fine on my laptop, but the second I connect to a machine, it doesnt input numbers. It will use the arrows that are on the number pad, but when num lock is on, no numbers work.
