Loading "On Ground" programmatically

Is there a way to load a free flight On Ground from a custom location programmatically?
either via Simconnect, wasm or JS ?

i’m trying with Simconnect_FlightLoad, but doesn’t seem to work
FlightPlanLoad doesn’t work either, it doesn’t respect the altitude (it loads the airplane at 1500ft upside down lol)

Related maybe?
