GPS shows disabled in QGC

I am porting the VectorNav VN3xx sample code to PX4 on a Pixhawk 4 and 5. I have replaced the Sensor Module with the VectorNav code and have all uORB topics being published. The one problem I see is that QGroundControl is showing GPS Disabled. I assume there is a particular uORB topic that is sent to the MAVLINK Module that needs to be updated properly.

Does anyone know which topic needs to be updated properly so that QGC reports GPS Enabled ?
