How to set an arbitrary url using the bitrix:catalog.smart.filter component?

Question

1C-Bitrix

I'm trying to implement hashtags through the "smart filter" component to filter products in the catalog.
The hashtag filter itself works fine, but I don’t understand how you can build an arbitrary url.
For example, when clicking on the hashtag "#metal", a url should be generated something like /catalog/category/ tag/ metal
