Good example page. Documentation on point. If you want to use Font Awesome icons in your application then this component is for you :-)

There are no conflicts when using this component with OutSystems built in Icons (98% implementation of FontAwesome 4.7).  This component has refactored all the FontAwesome 6 CSS class names from fa to fa6 as not to conflict with and existing FontAwesome CSS style sheets that the platforms or other components (IconsForEveryone, etc.) might include.

The only downside in using this component is that all icons are rendered as a generic icon within ServiceStudio (a limitation of OutSystems not exposing the same interfaces that they use in their internal components to user developed components).
