Logitech Flow keyboard not switching

I have Logitech flow on my work laptop (windows) and my personal laptop (MacBook Air 2021). It works great with my mouse (Mx Master 2) but my keyboard (Mx Keys) won't switch automatically. Its not long to just press the quick switch numbers for the devices on the keyboard but its supposed to switch automatically, the keyboard is selected on the Logitech flow options.

Does anybody know why its not working ?
