Mapping a remote controller keycode

[boresk]

I would like to map a button from a remote controller. For some reason, evtest and showkey is able to detect it (582, c00cf, KEY_VOICECOMMAND) but xev doesn't detect it.

How can sxhkd detect it? I suppose the easiest way would be to map the key to a keyboard key but I haven't found how to do so.
