How to use WrapperQuery in new Java API client 8.4.3 to fire a raw elasticsearch query?

I'm trying to use WrapperQuery to run a raw query like this

		String queryStr = "{\n" +
				"  \"query\": {\n" +
				"    \"bool\": {\n" +
				"      \"must\": [\n" +
				"        {\n" +
				"          \"match\": {\n" +
				"            \"type\": \"MyType\"\n" +
				"          }\n" +
				"        }\n" +
				"      ]\n" +
				"    }\n" +
				"  }\n" +
				"}";
		String encodedString = Base64.getEncoder().encodeToString(queryStr.getBytes());
		Query wq = QueryBuilders.wrapper(w->w.query(encodedString));

But get the below error when executing the search.
ErrorResponse: {"error":{"col":12,"line":2,"type":"parsing_exception","reason":"unknown query [query]","status":400}

However, if I remove the "query" element from the raw query JSON, I can execute the wrapper query.
E.g.

String queryStr = "{
    "bool": {
      "must": [
        {
          "match": {
            "type": "MyType"
          }
        }
      ]
    }
}"

gives me matching results.

Can you please provide an example to run a more complicated raw query having elements outside the "query" element like below:

String queryStr = "{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "type": "MyChange"
          }
        }
      ]
    },
  "size": 30,
  "from": 0,
  "sort": [
    {
      "change": {
        "order": "desc"
      }
    }
  ]
}
}"

Many thanks.
