I'm aware he already contacted me :)

There wasn't but I'm working on libifying it.

SnoreToast.exe also supported custom shortcuts, it does not run along 
side but you call it for each notification.

The api is msvc only so it is not possible to build the lib with mingw, 
while it would still be possible to call a external snoretoast.exe .

He proposed to integrate it in kdeconnect and later in knotifications, 
maybe a direct approach would be better.

As before you still need a special shortcut, I'd recommend to use 
Snroetoast.exe during the setup.

I could make the capability to install shortcuts available in the lib 
but... I'm not sure yet.

If no shortcut is registered libsnoretoast will report an error.
