How to display product categories with the Sale tag in woocommerce?

Question

WordPress

Good afternoon, colleagues!
I was given a non-trivial task, maybe some of you have come across and tell me how to proceed?
Generally. There is a catalog of goods www.lilians-kazan.ru/shop where categories of goods are displayed. There is a section "Sale" and there are products that are currently sold at a discount. But the customer wants a page with categories to be displayed there as in the main catalog, but these categories should be for those products that are currently discounted.
I would appreciate your help!
