TBS DroneCan UBX-M9140 - No Compass detected

I’m trying to get a TBS DroneCan UBX-M9140 working. The GPS functions work as advertised, however there is no compass showing in the hardware ID. The TBS Lucid manual is pretty sketchy on details for this module, except to say it includes a QMC5883 compass.

I’ve noticed there is no specific firmware for this module, it shows up as a generic ap-periph_gps. I didn’t see a specific firmware for it on the AP firmware site. I’m also running TBS Airspeed sensor and TBS PWM breakout boards (those both work) and they have named firmware.

I’m pretty novice with drone can setups, (other than getting Here3 and Here4 modules to work) so if there’s something basic I’ve missed don’t be afraid to say so.
