    Is loading from assetbundle supported?
    I'm using the ARFoundation!

    I tried set it from adressable but it was throwing an exception.

    below is my exception log:
    Code (CSharp):
    1.  [General] No resource group with name "ReferenceImageLibrary_F9826AB7-B00D-45C3-BB5E-C1090EB7CF4F" found

    My Solution:
    TIPS:We need to update the arfoundation & arkit to 3.0.

    This
    _handle.Result
    is load from assetbundle. and
    _handle.Result 
    is a ReferenceImageLibrary.

    Code (CSharp):
    1. MutableRuntimeReferenceImageLibrary tmp_RuntimeReferenceImageLibrary =
    2.                 ArTrackedImageManager.CreateRuntimeLibrary() as MutableRuntimeReferenceImageLibrary;
    3.             foreach (XRReferenceImage tmp_ReferenceImage in _handle.Result)
    4.             {
    5.                 JobHandle tmp_JobHandle = tmp_RuntimeReferenceImageLibrary.ScheduleAddImageJob(
    6.                     tmp_ReferenceImage.texture,
    7.                     tmp_ReferenceImage.name, tmp_ReferenceImage.width);
    8.                 tmp_JobHandle.Complete();
    9.             }
    10.  
    11.             if (tmp_RuntimeReferenceImageLibrary != null)
    12.             {
    13.                 Debug.Log("tmp_RuntimeReferenceImageLibrary: " + tmp_RuntimeReferenceImageLibrary.count);
    14.                 Debug.Log(
    15.                     "supportedTextureFormatCount: " + tmp_RuntimeReferenceImageLibrary.supportedTextureFormatCount);
    16.  
    17.                 ArTrackedImageManager.referenceLibrary = tmp_RuntimeReferenceImageLibrary;
    18.             }
    19.  
    20.             ArTrackedImageManager.enabled = true;
