Also note that with file at /etc/udev/hwdb.d/60-dell-mic-mute-hotkey.hwdb generated with the following content:
# Dell platform kernel driver
keyboard:name:Dell WMI hotkeys:dmi:bvn*:bvr*:bd*:svnDell*:pn*
KEYBOARD_KEY_150=f20 # Mic mute toggle
And with udev database updated: sudo udevadm hwdb -u
The microphone mute key works, but the mic mute led does not work.
(Also the icon is not correct, which show a speaker instead of a mic)

The microphone mute key does not work at all.
Key event cannot be captured by "xev" or "sudo showkey -s"
But keycode 248 would be returned when testing with sudo showkey -k
