Pair bluetooth mouse in both macOS and Windows 10 in dual boot???

I cannot for the life of me, pair my Logi Pebble mouse in macOS and Windows at the same time? I'm sure there is probably a way to discover the pairing code (under Windows) and install it into a .plist file in macOS startup???

I am currently also using a Logitech MX Anywhere S2 mouse with the dongle, as I cannot pair this in each OS at once?!

Anyone have a solution so I can get my USB port back again and go full Bluetooth mouse?! ?!

Any and all help/suggestions greatly appreciated...
