S3ExpressDirectoryBucketConfiguration

Proposed access control configuration for an Amazon S3 directory bucket. You can propose a configuration for a new Amazon S3 directory bucket or an existing Amazon S3 directory bucket that you own by specifying the Amazon S3 bucket policy. If the configuration is for an existing Amazon S3 directory bucket and you do not specify the Amazon S3 bucket policy, the access preview uses the existing policy attached to the directory bucket. If the access preview is for a new resource and you do not specify the Amazon S3 bucket policy, the access preview assumes an directory bucket without a policy. To propose deletion of an existing bucket policy, you can specify an empty string. For more information about Amazon S3 directory bucket policies, see Example bucket policies for directory buckets in the Amazon Simple Storage Service User Guide.
