Is it possible to use the TV remote w/CEC to change Kodi's volume?

I have my TV and an nexbox a95x-b7n (running 19.5-R3) connected, and the CEC is working so that I can use the directional, back, and ok/enter buttons without any issue. I have a dumb receiver connected directly to my a95x via spdif.

Is there anyway I can map the TV/CEC-remote volume buttons so that they change the volume in Kodi?
