How to make search results and facets use collapsed fields?

[PAK90]

I want to add this to the search;

      collapse: {
        field: "name",
        inner_hits: {
          name: "latest_document",
          size: 1,
          sort: [
            { releaseDate: "desc" }
          ]
        }
      },
      aggs: {
        "total_distinct": {
          cardinality: { field: "name" }
        },
      },

However adding it to the config for the SearchProvider doesn't work. Is it at all possible to make this library work with collapsed fields and with a custom aggregation for bucket counts? If so, how?
