How can I add Posystar Points?

var myComp = app.project.activeItem;

var myFillColor = [0.5, 0.5, 1.0];

var myPoint = 32;

var myShapeLayer = myComp.layers.addShape();

var myShapeLayerContents = myShapeLayer.property("ADBE Root Vectors Group");

var myShapeGroup = myShapeLayerContents.addProperty("ADBE Vector Group");

var myStar = myShapeGroup.property("ADBE Vectors Group").addProperty("ADBE Vector Shape - Star");

var myShapeFill = myShapeGroup.property("ADBE Vectors Group").addProperty("ADBE Vector Graphic - Fill");

myShapeFill.property("ADBE Vector Fill Color").setValue(myFillColor);

//How can I add  Posystar Points

myStar.property("ADBE Polystar Points").setValue(myPoint);
