Fontawesome Pro support via adding a license.
Elementor has this very nice feature that if I add my FA license then I get access to all icons provided by FA - love it!
Oxygen has a more oldschoold approach, but it works. Here I have to download icons and then upload them, but it works.
Bricks has no option for that. I have looked through the theme code and tried to manipulate it my self, but it didnโt work.
Hope for a version like Elementor soon.
