Hello Antonio, I'm Johrelle a fellow Windows/Microsoft user. I'm happy to assist you.
Make sure you have installed the Boot Camp drivers for Windows 10. These drivers are usually included when you set up Boot Camp using Boot Camp Assistant on your Mac.
Alternatively, you can use the Magic Mouse Utilities: https://magicutilities.net/download
It's a third-party program designed to enhance the functionality of your Magic Mouse, particularly when used on a non-native system like Windows 10 with Boot Camp.
