Help，How to get the LongitudeLatitudeHeight or ECEF of the mouse position?

I try to LineTraceSingleByChannel, but it is inaccurate!!

First you can get the world coordinate of the mouse position use ConvertMouseLocationToWorldSpace, then with Cesium georeference, InaccurateTransformUeToLongitudeLatitudeHeight or InaccurateTransformUeToECEF will transform world to the longitiude and latitude.
