How JSFL Sends Graphics to The Stage

I made jsfl.

Call JSFL using SWF.

Swf and JSFL are both put into the path

C:\Users\myname\AppData\Local\Adobe\Animate CC 2019\zh_CN\Configuration\WindowSWF

I need to add graphics from SWF to the Stage.

Click the button in SWF to copy the graphics displayed in the SWF to the Stage.

I hope i can get an answer.
