Issues with Security Analytics and indexes/shards

Hi guys, we are having an issues with security analytics plugin and it having created hundreds of indexes with thousands of shards - causing us to hit our cluster shard limit. Even after removing the dectors the indexes don’t get cleaned up.

More information on the GitHub issue here: Security Analytics DNS created hundreds of indexs with thousands of shards hitting limit, deleted dectors but indexes are still present · Issue #667 · opensearch-project/security-analytics · GitHub

Our cluster has over 30TB of data in it, so rebuilding it is not really an option for us presently - can anyone help with how to clear out all the security analytics internally created indexes etc? We are running on AWS managed service so uninstalling the plugin is not possible.
