Atlas search with in operator on type embeddedDocuments.

Hi everyone, Below search index is created with sample document provided below mapping snippet

  "mappings": {
    "dynamic": false,
    "fields": {
      "distributor": {
        "type": "embeddedDocuments",
        "dynamic": false,
        "fields": {
          "distributorName": {
            "analyzer": "keyword_lower",
            "type": "string"
          }
        }
      }
    }
  },
  "analyzer": "lucene.standard",
  "searchAnalyzer": "lucene.standard",
  "analyzers": [
    {
      "charFilters": [],
      "name": "keyword_lower",
      "tokenFilters": [
        {
          "type": "lowercase"
        }
      ],
      "tokenizer": {
        "type": "keyword"
      }
    }
  ]
}

//Sample document

{
   "_id": "d2f1dea6-6bb0-4a6f-854b-ceacc6284cd1",
   "distributor": {
     "distributorName": "MEXICO",
     "distributorCountryCode": "`1",
     "distributorGroup": "TM"
   }
  
 }

I want to use in operator with Atlas $search. Below query is working fine

    $search: {
      index: "default",
      compound: {
        must: [
          {
            embeddedDocument: {
              path: "distributor",
 
              operator: {
                compound: {
                  must: [
                    {
                      text: {
                        path: "distributor.distributorName",
                        query: "MEXICO",
                      },
                    },
                  ],
                },
              },
            },
          },
        ],
      }
    },
  }

but I want to use it using in operator for multiple inputs. Is it possible? I tried with below query using in but giving empty result.

  {
    $search: {
      index: "default",
      compound: {
        must: [
          {
            embeddedDocument: {
              path: "distributor",
              operator: {
                compound: {
                  must: [
                    {
                      in: {
                        path: "distributor.distributorName",
                        value: ["MEXICO"],
                      },
                    },
                  ],
                },
              },
            },
          },
        ],
    }
