Use S3 elastic plugins

Hi:

I installed elastic operator to install elastic search and kibana in AWS EKS.
I would like to register a S3 Repository for taking snapshot.
How do I get the repository-s3 plugin added to the elastic search image?
I used kubectl exec -it quickstart-es-default-0 /bin/bash and noticed the plugins directory is empty.
Elastic 7.5.0 image is in use.

Found the document myself now. https://www.elastic.co/guide/en/cloud-on-k8s/master/k8s-init-containers-plugin-downloads.html
