Editing builder page with Elementor

Hello Villatheme team,

Is there any tutorial that’s been made to edit the builder page with Elementor? I can add it to a page with a shortcode but I cannot edit any of the text sizes or colors as it displays as if the builder is empty. I do not have access to the theme file list to edit the files that way nor do I fully understand the tutorial given in the documentation. My goal is to be able to edit the text sizes for the widgets; the original color of the product links; and the step list background with the forward and backward buttons as well.

Thanks
