Playcanvas Morph java script

I looking for a java script that will morph an object in Playcanvas.  When the fbx file gets up loaded into playcanvas both the base object and the morph target object are loaded as separate objects.  Per Playcanvas support all information is availble when the fbx file is up loaded, morph does not work.  Anyone have a scrpt that will morph a base object and a morph object?
