Hi Community,

I encountered strange behavior with a new Elasticsearch Java client.

Before, I used org.elasticsearch:elasticsearch:7:8:1  
`WrapperQueryBuilder wrapperQueryBuilder = new WrapperQueryBuilder("string")` to get a wrapped query with Base64.

Now, I decided to use a new client co.elastic.clients:elasticsearch-java:7.17.22 and the same logic

```auto
WrapperQuery.Builder wrapperQueryBuilder =
              QueryBuilders.wrapper()
                      .query("string");

```

Unfortunately, I did not get the old result. It means I have to use Base64Encoder or use another builder to get Base64?
