Like Duct Tape said, the remote IR is just for controlling an IR TV. The remote is Bluetooth so URC isnt going to be able to help much:[Link: store.google.com]
Its the same problem I am having with the Tivo Stream 4K. Its an amazing device but a BT remote. I did try a Flirc USB dongle via a USB A to C adapter on it but it only partial works (U/D/L/R).
You could try something similar on yours to see if you have any luck.
