Using FontAwesome 5 with get_icon()

I am trying to create widgets for a client’s Elementor plugin and have been trying to use FontAwesome 5 in the widget selection pane. I am using the free version of Elementor, version 3.4.7. I am using get_icon() to select the icon as in:

public function get_icon() {
  return 'fab fa-github';
}

However, the icon does not display. I have turned off support for FontAwesome 4 and this does not help. Could you please advise what I need to do to display FontAwesome 5 icons in the editor? Do I need to add something else to load the FontAwesome files? They display in every other area, just not here, and it is rather frustrating.
