I'm guessing that the OEM controller on your 2019 GMC Sierra 1500 is a proportional brake controller. This means that unless you are moving it won't apply the trailer brakes when you step on the brake pedal. Since the Titan Disc Brake Kit and BrakeRite Electric-Hydraulic Actuator # T4843800 are activated with the Adapter Module for BrakeRite EOH Actuators # DX35FR installed when you use the manual override or pull the breakaway pin it leads me to believe that your brake controller doesn't sense the need to apply the brakes while sitting still.

Try driving slowly with your trailer connected and then press the brakes to see if that makes a difference. If it doesn't let me know and I can help you troubleshoot further.
