Fetch the products of a category or a virtual category by a slug property instead of the id

Description

In the case I have to retrieve the products of a given category where I only know the url_key (defined as an additional attribute for my categories), I need to make two requests. One that filters the categories according to my url_key.
The concrete call is:
query getCategory { documents(entityType: "category", localizedCatalog: "com_fr", filter: {equalFilter: {field: "url", eq: "weekends-by-the-river"}}) { collection { data } } }
And then from the response, I get the category id to make the second request which retrieve the products:
query getProducts($requestType: ProductRequestTypeEnum!, $localizedCatalog: String!, $currentPage: Int, $currentCategoryId: String, $pageSize: Int, $search: String, $sort: ProductSortInput) { products: products( requestType: $requestType localizedCatalog: $localizedCatalog currentPage: $currentPage currentCategoryId: $currentCategoryId pageSize: $pageSize search: $search sort: $sort ) {...})
with the variables as is:
{ "currentCategoryId": "my_category_id", "currentPage": 1, "localizedCatalog": "19", "pageSize": 10, "requestType": "product_catalog" }

It would be easier if the categories would be fetchable by slug or url_key, because from a frontend perspective, it's important for the SEO score to have an explicit url.
