PTT Question - Digirig / Baofeng HT / Fldigi on RPI4

I am working with DigiRig / Baofeng H6 / GPredict to play on satellites.

I can’t figure out how to get it to work. GPredict uses HAMLIB and Baofeng doesn’t show up as a supported radio.

Does anyone have any tips on A. How to even get the rig working with any piece of softare - I have FLRig and others. B. Any ideas on getting it to work with HAMLib?
