Hello there,
If you set "create_desktop_shortcut": true, this policy will create a desktop shortcut immediately after you apply it. Then, every time you open a new Edge session (including the web app window, and make sure there's no existing Edge session), you'll have a new shortcut copy.
I have a workaround for you to avoid redundant shortcuts being created. You need to delete "create_desktop_shortcut": true or change its value into false after the original shortcut was created. Then, no redundant shortcuts will be created.
