[ARCore] Depth occlusion doesn't work for translucency objects.

I succeeded to occluded objects by ARCore depth in UE4.26. That’s a very exciting feature!!
However It looks translucent objects is not occuluded by depth. Please see the Contact Shadow. Is there anyway to solve that?

I made build the HandheldAR sample. and enabled UseSceneDepthForOcclusion, modified EnabledSessionTrackingFeature to SceneDepth in D_ARSessionConfig.
