IR Remote ZXT-120 Driver?

This driver is the last piece of the puzzle for me, then I can finally disconnect SmartThings.

I'm not a developer either, so I wouldn't even know where to begin with trying to get full functionality back to this driver.

I tried going through this thread: https://community.hubitat.com/t/app-and-driver-porting-to-hubitat/812

Needless to say, I was lost. Any help out there?

Thank you!
