woocommerce - products by category slug? [closed]

Question

good morning, I need to display the shop base page in a category layout,meaning first show all the products from category A and beneath it all the products from category B and so on.. I trying to use the built-in woocommerce shortcode -"products by category slug" but instead it displays products by products slug,what is the solution?

here is the shortcode

[product_category category="" per_page="12" columns="4" orderby="date" order="desc"]

thank you
