Buzzer support on ArduRover for Omnibus F4v6

I wonder if buzzer is supported through the Bz+/- pads on the Omnibus F4v6 board?
I have connected a buzzer on my board but it is very quiet. Although it could be due to a faulty buzzer I would like to know if it is supported or not.

Thanks,
Ulf

any luck getting buzzer to work?
