Could you add a comment that normally you'd want to show a dialog (as per the
function name).
But you don't because on Mac you always create a shortcut in /Applications.

Done.

Not really, we only publish to /Applications (see CL description). Agree that
this could use some explanation in comments.

removed this code.

+  web_app::CreateShortcuts(shortcut_info);
