2019 Nvidia Shield Pro

Anyone figure out how to connect to the 2019 Nvidia Shield Pros? I can program my 2015/2017 Shields with standard Kodi commands using http but for some reason I cannot get any commands into the 2019 Pro model. I may have to go the FLIRC route but then I will have to completely program the flirc with new IR codes.

I may have to fish out my Harmony remote hub but I really, really, really don’t want to use that thing.
