Hi @ankitkala

Looks like, unlike other plugins, the ccr plugin zipfiles do not get published anymore at this link -
https://aws.oss.sonatype.org/content/repositories/snapshots/org/opensearch/plugin/opensearch-cross-cluster-replication, even though i see build.sh has the publish task.

Can you pls guide here on what is missing?

Just to clarify, if user wants to use CCR in ISM in a security enabled cluster, they will still need the internal replication action allowed, right?
