You can sort of remap it on windows, but it's somewhat limited in my experience. It shows up as a keyboard chord rather than a simple button press. I think it's LWin+LShift+F23. I ended up simply disabling it entirely on my gaming laptop. I've been meaning to see if it's easier to make it useful on KDE Plasma desktop but haven't yet (though I did remap the HP Omen button to pull down Yakuake instead).
