Help, WP theme Webify and Elementor

Hi guys, I just bought the theme Webify from Envato and work with Elementor. I’m not super experienced yet but it’s great to work with. I haven’t bought the Pro version yet by the way.
Now I have a text in an Icon box that I want to refer to with a < a ref… > instruction but that doesn’t work. Do I have to buy the Pro version?
