PX4 based servo control with AUX port using QGC

Hello

I want to run the servo using RC controller and AUX port.

After connecting a separate battery to the motor, AUX1’s signal pin is connected to the motor.

We are in the process of setting using Qgroundcontrol, but I am not sure what parameters or separate settings to touch.

Please help me if someone has already tried, or if you can give me any advice regarding this.
