I would like to prepare a .ppa file to copy a shape from addin to any PPT file I want.

So I write:
Application.addins("xxx").slides(1).shapes("yyy").copy
here xxx is my file name - xxx.ppa and yyy is the name of shape.

however, it does not work after I save it into addin.

How to fix that?
If the slide would be removed after saving as Addin?
