iPad as a second screen on a work MacBook Pro

I was trying to see if I could enable my iPad as a second screen on my work MacBook. Pro like I use it for my personal MacBook Pro, however I found in a ￼support document￼ that you must have an iCloud account connected to use the continuity feature. Unfortunately, my IT department doesn’t allow me to log in to any iCloud account, so I’m stuck with a digital divide between my MacBook Pro and iPad Pro.
