KML clampping to 3Dtiles

[11115]

Hi Omar.
Is it kml clamp to 3dtiles working now??
It seems not working for me
my code is below

    var options = {
		camera : viewer.scene.camera,
		canvas : viewer.scene.canvas,
	};
	var kml = viewer.dataSources.add(Cesium.KmlDataSource.load('/project/autodesk/3dtiles/auto_line_kmz.kml', options));

Thank you
