How to add WooCommerce product variations to sitemap?

Question

Search Engine Optimization

There is a WP Rocket plugin that preloads website pages based on a sitemap. The sitemap is generated by the Yoast SEO Premium plugin plus Yoast SEO: WooCommerce is installed. Because the WooCommerce Show Single Variations by Iconic plugin also displays product variations in the catalog, and users follow links ending in ?attribute_pa_color=red , respectively. And I would like to cache these pages. How to do it? How can I add links to the sitemap not only to parent products, but also to variable ones (their variations)?
