Magic Mouse 2 on Windows10/Bootcamp

Hi, I'm having problems trying to use Magic Mouse 2 on Windows 10 on Bootcamp.

MBP15 early 2015, Bootcamp and Windows 10 installed using original macOS in 2015, actually updated to Big Sur. Windows 10 is already updated.

The main problem is that scroll doesn't work at all in Windows 10, then I downloaded using Bootcamp Assistant from macOS, latest Support files, moved to Windows partition and installed only AppleWirelessMouse64.exe. Nothing is changed, mouse works but without scroll.

Another poin is about how is handled by Bluetooth...

If I switch off MM2, rebooting into Bootcamp/Windows 10 MM appear as paired and connected... but naturally doesn't work cause it's switched off.

If MM2 is on during reboot in Win10, same situation, MM appear paired and connected but doesn't work. At every reboot in Windows I have to remove MM2 from BT devices and do a new pairing.

Thanks in advance for your help.
