Use EKS for saving snapshots

I am trying to save grafana snapshots on my EKS infra. I couldn’t find any documentation for the same.
All I know is enable snapshots and set external url in grafana config.
How should I configure EKS for the same?
Is there any documentation for that?

AWS EKS is not a storage service. Usually AWS S3 is used as snapshot storage.

So, I just have to configure the s3 endpoint in my eks grafana config. is that it?
Also, how can I setup authentication on this?
