I am using .Net 6.0, running Elastic.Client 8.x connecting to 7.17 ES, which will be shortly upgraded to 8.4. I want to know how do I perform bulk indexing of raw json data? I could see some example under Java client documentation. But I don't see any documentation or example of how to achieve this using .Net client or even confirmation that similar support is available on .Net client. There are separate process that is building System.Text.Json.Nodes.JsonObject for me for each input record. So there is no fixed model that I will use as this is supposed to be a generic process. Can you please let know, how can this be using using the new 8.x client?
