Herelink Controller Unit - RPM parameter


I would like to ask for help with the display of the RPM parameter on the Herelink Controller Unit. I installed a Hall sensor on the BLDC motor. I connected this sensor to the AUX - GPIO pin on the Orange Cube. I can see the value of the RPM1 parameter in the Mission Planner software on the PC. I would like to monitor the RPM value on the Herelink Controller Unit display. Unfortunately, there is no possibility to select the RPM parameter in the “Instrument Panel” window in QGroundControl software on the controller. Other parameters such as altitude or ground speed can be selected there.

Is it possible to display the RPM parameter on the Herelink Controller Unit? If so, how can this be done?
