How to get information about a discount on a product in Umi Cms?

Question

XSL & XSLT

Good day everyone. There was such a dilemma:
you need to display an additional block in the product card if this product is sold at a discount. Inside the product editing section, I see that this can be tracked by the presence of the Sale filter for this product.

Is it possible to track this somehow in the product card? I know that we can display the properties of a product, but I can’t imagine how to understand that it is included in some kind of filter ...
