Unable to get Coordinate System with new Open XR and MRTK3

[tranquanglam123]

I am doing the same project, and I use this reference solution #10082 (comment) to get the coordinate system:

#if ENABLE_WINMD_SUPPORT
Windows.Perception.Spatial.SpatialCoordinateSystem unityWorldOrigin;
#endif

private void Awake()
{

#if ENABLE_WINMD_SUPPORT
SpatialCoordinateSystem unityWorldOrigin = PerceptionInterop.GetSceneCoordinateSystem(UnityEngine.Pose.identity) as SpatialCoordinateSystem;
#endif

But it always return null.

Expected behaviour:
The function returns the coordinate system

Unity editor version
Unity 2022.3.21f1

Mixed Reality Toolkit
MRTK 3
