I'm using this command
'/Applications/Google Chrome.app/Contents/MacOS/Google Chrome' --user-data-dir=/foo/bar
to launch a separate instance of Chrome which I use solely for chat (WhatsApp, Messenger, etc.) which is very handy, but when I Command-Tab to switch between it and my primary Chrome instance they both have the same icon.
Is there any way to use a custom icon for this instance?
(I know about apps like Franz and Rambox but they don't allow the use of certain text Services which I need.)
