How to add a new button, you can continue to overlay

Your question is ambiguous.
In your example, you are pointing to a ISwitch, not a IButton.

What I want to ask is how to create new buttons constantly. This is the function of camera storage under the drawing menu. I want to create such a function through scripts.

Ha ok, I see now, it’s a dropdown menu, you must use the ZFileUtils :
