Elasticsearch function_score not working inside nested aggregations

Elastic Stack Elasticsearch
1

I have an Elasticsearch query with nested aggregations. It was working as expected but when I added a function_score query it seems to not take it into account.

This is my query:

GET reviews/_search
{
  "size": 0,
  "aggs": {
    "media": {
      "filter": {
        "term": {
          "profileId": "uuid"
        }
      },
      "aggs": {
        "items": {
          "filter": {
            "exists": {
              "field": "gallery"
            }
          },
          "aggs": {
            "top_reviews_gallery": {
              "filter": {
                "bool": {
                  "must": {
                    "function_score": { //same behaviour as top_reviews_gallery.filter.function_score
                      "functions": [
                        {
                          "filter": {
                            "term": {
                              "version" : "5.5.9"
                            }
                          },
                          "weight": 1000
                        }
                      ]
                    }
                  }
                }
              },
              "aggs": {
                "media_items": {
                  "top_hits": {
                    "size": 100,
                    "sort": [
                      {
                        "timestamp.createdAt": {
                          "order": "desc"
                        }
                      }
                    ]
                  }
                }
              }
            }
          }
        }
      }
    }
  }
}

I do not get any error but reviews with version attribute higher than 5.5.9 have higher score and are returned first
