I'm using the Elastic.Clients.Elasticsearch NuGet package to migrate away from our existing Nest implementations. I have been unable to find histogram in the new docs or source. We have searches that utilize the histogram `extended_bounds` object. It seems to be missing from the `Serialize` methods on the various types of histogram.

Is it possible to add `extended_bounds` using the 8.13.5 .NET client without hand-coding the entire search?

Hi @Kyle_Manuel,

this field is currently missing, but I'll working on this in the beginning of next week. Related issue on GitHub: [ExtendedBounds missing from DateHistogramAggregationDescriptor\<TDocument\> · Issue #8122 · elastic/elasticsearch-net · GitHub](https://github.com/elastic/elasticsearch-net/issues/8122)
