Dragging an object but leaving it at the original layer

Hi there,
I am using this code in Adobe Animate to drag a green slider under yellow windows.

this.stop();
this.greenSlider.visible=true;

const greenSlider = zimify(this.greenSlider)
greenSlider.center().drag({all:true});

At the moment, when I click on the slider to drag it it moves to the top layer .... see diagram.

Is there a way that I can keep the slider below the yellow windows?

set the onTop:false on the drag
