[Bug]Libra Mini Can't Output Mouse Button Presses on Vial

[sodiumtritide]

The joystick moves the cursor with true analog input with the Vial firmware flashed, but the mouse button presses do not register even after mapped to the Libra Mini in Vial.

I am having similar issue with the libra mini not being able to send media controls like volume up and down or media previous and media next. I know it's not the exact same thing, but I thought it was similar enough that it would be worth mentioning

Have you tried adding the line MOUSEKEY_ENABLE = yes to your rules.mk file for the firmware that you're compiling? I don't believe that it is added by default so it should in theory solve your problem. I had this issue with my media keys not working, but I didn't realize that I had to add the EXTRAKEY_ENABLE = yes.
