1. We go to the "Your campaign" section of Cool Tabs, click on "Create campaign" and install the External Content Tab application.
2. We include the name that we want to give to the tab in the basic data and in the Url configuration (point 2), we add the url of the page that we want to show. The height of the content can also be adjusted, but if it is greater than 1280 pixels, a scroll bar will appear.
3. Do not forget the name (and icons and name of app, if you publish in White Label).
