Hello,
As you know the default Archive pages come from WooCommerce by default. So, you can’t edit them directly with the Page Builder plugins like Elementor or WPBakery. So, you can make use of the WoodMart Layout Builder to create Custom Archive pages layout and in that you can add Products widget like you have mentioned of the referenced Site at the bottom and select your choice of Products there.
You can read more about it here: https://xtemos.com/docs-topic/woodmart-woocommerce-layout-builder/
