NOTE: The core features of Active Storage require the following permissions: `s3:ListBucket`, `s3:PutObject`, `s3:GetObject`, and `s3:DeleteObject`. If you have additional upload options configured such as setting ACLs then additional permissions may be required.
NOTE: If you want to use environment variables, standard SDK configuration files, profiles,
IAM instance profiles or task roles, you can omit the `access_key_id`, `secret_access_key`,
and `region` keys in the example above. The Amazon S3 Service supports all of the
authentication options described in the [AWS SDK documentation]
