@Dharin-shah thanks again for your contribution to OpenSearch. Any interest in helping us add the documentation to the website for this feature here? Unless I missed it we haven't documented this feature yet. It did unfortunately miss the 2.12 release but it will be included in 2.13.

Apologies, I did in fact miss it from #6278! I'm closing this issue.
