Change icon and group in task bar by instance

[digitalsignalperson]

I just went through these https://askubuntu.com/questions/493142/can-i-put-two-chrome-different-users-on-my-launcher https://github.com/felipecrs/dotfiles/blob/master/scripts/create_alternative_chrome_shortcut.sh

and found the last script created a desktop file I could further modify to

• set the Name=Chromium-MyThing
• change the icon to distinguish from default chromium

Would be cool to integrate with chrome-private in some way ability to automagically change the chromium icon (blue, green, red, purple, ... etc.) and keep windows of the different instances grouped separately.
