Fingerprint scanner driver for Lenovo C940? If not, how to make one?

reddit

I've looked in quite a few places but can't find a driver for my Lenovo C940's fingerprint scanner. I'm running Ubuntu 20.04 and am fairly new to the whole linux ecosystem. If someone could point me towards one that would be great.

If not, I'm fairly experienced with programming and wouldn't mind delving into the low-level stuff and trying to code a driver so I can contribute if someone could just point me in the right direction that would be great!

I'm pretty sure I tried to the driver here https://www.reddit.com/r/linux/comments/eeoyhi/the_fingerprint_reader_finally_works_on_the/ but to no evail
