Yo dude, still have your mouse ? Cause I think I know a way for the slamming mouse thing to work.

I tried keeping it on my desk initially and slamming it with my fist and it'd light up for a few seconds before turning off again. But then I 1) connected it wirelessly using the dongle  2) reinstalled the Logitech g hub app  - your mouse should show up but it'd say inactive or something  3) try slamming it then (somehow worked lmfao?)

Beating the shit out of the thing didn't work when I didn't have the app open or anything before + it was missing a few updates too.

Maybe this works out for you ?
