I am trying to add an authentication method to AWS OpenSearch.
By default it comes with basic auth with internal db,
I would like to configure Security Plugin with a second authentication mechanism OpenId Connect
Documentation says to use Update Security Configuration , which doesn't seem to be allowed by AWS.
tried PUT _plugins/_security/api/securityconfig
and PUT _plugins/_security/api/securityconfig/authc
both seems to be failing with {"Message":"Your request: '/_plugins/_security/api/securityconfig/authc' is not allowed."}
Is there an alternative, all I want to do is , use JWT Token(from OpenID Connect Cognito) to run OpenSearch _search API, rather than using internal database basic auth or IAM Role from Federated Pool.
