Display a web application in the cockpit application menu

With cockpit we now have to make some changes to display our web application inside the application menu of cockpit. You have to test and make a lot of attention to the sudoers.d/files, it could break the server-manager, so add an empty line at the end of the file, and please test it carefully delegated to a simple user.

you can use this as example

you must set as executable the api/read
Rename the icon of your web app to logo.png

Then the web app must be delegated to the group of the user if you want your user use the html link
