We were using the Rest High Level Client before and below was the usage to access the aggregation buckets from the SearchResponse

```auto
 	ParsedStringTerms aggregation1 = searchResponse.getAggregations().get(AGGREGATION1.name);
    for (Terms.Bucket bucket : aggregation1.getBuckets()) {
      for (Aggregation aggregation2 : bucket.getAggregations()) {
        List<? extends Terms.Bucket> buckets = ((ParsedStringTerms) aggregation2).getBuckets();
        // do something with the subaggregations
      }
    }

```

How do we go about accessing it in the new version of Java Client API ?

> **[Variant types | Elasticsearch Java API Client \[8.10\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/8.10/variant-types.html)**

I do see these mention to use \_custom to access these buckets ? Is there any other way to access these buckets ?
