How can I manually add the beats composable index templates?
The instructions here: Load the Elasticsearch index template | Winlogbeat Reference [7.15] | Elastic only export the legacy template.
I prefer to review the index templates before loading them into Elasticsearch, so exporting them to a file is the only way to do that. I would also like to start using composable templates, but there doesn't seem to be a way for beats to export to a file except for the legacy template.
