About adding new parameters of attitude controller in Ardupilot SITL

I designed a new controller in addition to the copter’s attitude controller. Various parameters have been added to implement the function, but it has been confirmed that the current board is uploaded and operating normally.

Before the flight test, SITL was performed to check the regular operation of the code.

However, the parameter has not been added to SITL’s parameter editor. (Checked in Apmplanner after uploading to Pixhawk)

Are the parameters added from the library folder not loaded from SITL?
