How to swap bluetooth dongle of 2 different M235 logitech mouse

Hi,

one of my mouse stoped working (M235 blue color). I have a spare mouse (M235 Grey) working condition but blue tooth dongle is missing.

I am planning to swap the blue tooth dongle of these to so that one of it can be used.

If someone knows how to identify the receiver on the board, than i will swap them and make the mouse functional...........

Plz share your valuable inputs & help resolve the issue.

Thanks,
