The plugin does not show me the attributes and their variations on the product l

Hello, good morning, cordial greeting. I have configured the plugin following the documentation so that the color and material variations of my products appear on any category page or product listings. I have tried every way and I can’t see the color picker on my product listing page. I am using the Products Grid widget from JetWooBuilder and I would like to know if with some shortcode or is there another way to add the variations just below each product. Please if you can help me. The list of products in my store works by presenting an archive page of my products organized by category. Please see the example of the product called “RING WITH 5 SKULLS” that appears at the end of the page of this product category (enclosed in red in the attached image) as it is the only one that has material and size attributes. I need the specified materials for this product to appear in the product listing and not just on the sinlge product page.
