The following policy grants a user access to manage a specific bucket in the Amazon Lightsail object storage service.
This policy grants access to buckets through the Lightsail console, the AWS Command Line Interface (AWS CLI), AWS API, and AWS SDKs.
Users who don't have this policy will experience errors when viewing the Objects tab of the bucket management page in the Lightsail console.
