Is there a way to have a little icon on the menu bar or a shortcut from the keyboard to turn on/off internet sharing on MacOS Catalina? I tried with automator but no results...

Turning on Internet Sharing also requires that you to select a port to use it on, and from a list of ports used by other computers that can use that sharing service. Simply toggling the Internet Sharing button does not complete these other two tasks.

AppleScript solutions written in 2010 do not magically do this for you either because Apple keeps changing its preferences panels.
