I really need some help because ,im stuck at a place creating a compound shape for a rigid body, I went threw js-tests but in that there is no examples showing how to make a compound shape but in cpp-tests there is a function used to create compound shape i really need to know how to implement it in javascript

like we add other shapes ex:
new jsb.Physics3DShape(jsb.Physics3DShape.ShapeType.SPHERE,1)

how to give the list of shapes in such a way
new jsb.Physics3DShape(jsb.Physics3DShape.ShapeType.COMPOUND,??)
