Ublox Gps with navigator board and ardusub

I just received the blue robotics navigator flight controller and was trying to setup the sparkfun gps - SparkFun GPS-RTK-SMA Breakout - ZED-F9P (Qwiic) using the Serial 3 port but Its not able to recognize the gps, when checking Mavlink Inspector I do not get any data. I do not know what I’m doing wrong. Any help would be greatly appreciated.
