// Applies an Amazon S3 bucket policy to an Amazon S3 bucket. Directory buckets -
// For directory buckets, you must make requests for this API operation to the
// Regional endpoint. These endpoints support path-style requests in the format
// https://s3express-control.region_code.amazonaws.com/bucket-name .
// Virtual-hosted-style requests aren't supported. For more information, see
// Regional and Zonal endpoints (https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-express-Regions-and-Zones.html)
// in the Amazon S3 User Guide. Permissions If you are using an identity other than
// the root user of the Amazon Web Services account that owns the bucket, the
// calling identity must both have the PutBucketPolicy permissions on the
// specified bucket and belong to the bucket owner's account in order to use this
// operation. If you don't have PutBucketPolicy permissions, Amazon S3 returns a
// 403 Access Denied error. If you have the correct permissions, but you're not
// using an identity that belongs to the bucket owner's account, Amazon S3 returns
// a 405 Method Not Allowed error. To ensure that bucket owners don't
// inadvertently lock themselves out of their own buckets, the root principal in a
// bucket owner's Amazon Web Services account can perform the GetBucketPolicy ,
// PutBucketPolicy , and DeleteBucketPolicy API actions, even if their bucket
// policy explicitly denies the root principal's access. Bucket owner root
// principals can only be blocked from performing these API actions by VPC endpoint
// policies and Amazon Web Services Organizations policies.
//   - General purpose bucket permissions - The s3:PutBucketPolicy permission is
//     required in a policy. For more information about general purpose buckets bucket
//     policies, see Using Bucket Policies and User Policies (https://docs.aws.amazon.com/AmazonS3/latest/dev/using-iam-policies.html)
//     in the Amazon S3 User Guide.
//   - Directory bucket permissions - To grant access to this API operation, you
//     must have the s3express:PutBucketPolicy permission in an IAM identity-based
//     policy instead of a bucket policy. Cross-account access to this API operation
//     isn't supported. This operation can only be performed by the Amazon Web Services
//     account that owns the resource. For more information about directory bucket
//     policies and permissions, see Amazon Web Services Identity and Access
//     Management (IAM) for S3 Express One Zone (https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-express-security-iam.html)
//     in the Amazon S3 User Guide.
//
// Example bucket policies General purpose buckets example bucket policies - See
// Bucket policy examples (https://docs.aws.amazon.com/AmazonS3/latest/userguide/example-bucket-policies.html)
// in the Amazon S3 User Guide. Directory bucket example bucket policies - See
// Example bucket policies for S3 Express One Zone (https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-express-security-iam-example-bucket-policies.html)

// HTTP Host header syntax is s3express-control.region.amazonaws.com . The
