By the way, this keyboard seems to be supported by the Linux Vendor
Firmware Service [1]. So you should be able to use `fwupdmgr refresh` and
`fwupdmgr update` to update the firmware.

The uploaded versions look older than the ones you have though.

Version MPK01.02_B0021
Version MPK01.03_B0024

Some desktop environments also integrate that in their graphical update

Kind regards,
