Hey JJ – David Waumsley has an excellent article on adding Font Awesome icons to your menus. It’s focused on adding social icons but you can use the same technique, maintaining the text in your menu and adding the appropriate icon as you need – see the full article here: https://davidwaumsley.com/icons-to-beaver-builder-theme-menus/
Alternatively, you can use the very excellent Font Awesome 4 menus plugin and follow the advice here on setting it all up.
