[Persistence] How to Store Edited Flows to Specific Elasticsearch Index

Hi there, I'm just a newbie to ELSA. As far as I know, the edited flows are stored in Sqlite on my local device. If I want to store persistence data to specific ES server and specific ES index. I didn't see any documentation about this setting. I think I need to set

- Server Endpoint, ex: http://xxx.com
- Username
- Password
- Index Name

And how do I debug for the request ELSA sends to the ES server?

Thank you
