Upower doesn't support Logitech g700s

I'm not able to see the battery status of my Logitech g700s mouse as it uses a different receiver from most other Logitech HIDs. My K800 and M570 on a unifying receiver both work.

Here is the receiver:
Bus 002 Device 004: ID 046d:c531 Logitech, Inc.

And as the mouse can also work on a wired connection, here is the mouse itself:
Bus 003 Device 003: ID 046d:c07c Logitech, Inc.
