Hello,

I am trying to make a query using auto\_date\_histogram and extended\_bounds but i get the error:  
` [auto_date_histogram] unknown field [extended_bounds]`

the documentation for auto\_date\_histogram does mention extended\_bounds in the note but I can't figure it out. here is the documentation I am looking at where it mentions extended\_bounds:

> **[Auto Date Histogram Aggregation Usage | Elasticsearch .NET Clients \[7.16\] |...](https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/auto-date-histogram-aggregation-usage.html)**

here is my query:

```auto
