How to get maximum double value from ParsedMax elasticseearch

Question

I older version of Elasticsearch 5.x, we used the class ParsedMax.getValue() method to get maximum Double value from the object as follows

Double val = Double.valueOf(parsedMax.getValue());

Now, we are upgrading to the newer elasticsearch version 8.3.3 and we found this method doesn't exists. How can we achieve this in newer version

I think that in version 8.3.3, the method changed from getValue() to value().

The class ParsedMax now inherits from the class: ParsedSingleValueNumericMetricsAggregation which uses the interface NumericMetricsAggregation.SingleValue which has the method value().
