// This operation is not supported by directory buckets. Returns the Cross-Origin
// Resource Sharing (CORS) configuration information set for the bucket. To use
// this operation, you must have permission to perform the s3:GetBucketCORS
// action. By default, the bucket owner has this permission and can grant it to
// others. When you use this API operation with an access point, provide the alias
// of the access point in place of the bucket name. When you use this API operation
// with an Object Lambda access point, provide the alias of the Object Lambda
// access point in place of the bucket name. If the Object Lambda access point
// alias in a request is not valid, the error code InvalidAccessPointAliasError is
// returned. For more information about InvalidAccessPointAliasError , see List of
// Error Codes (https://docs.aws.amazon.com/AmazonS3/latest/API/ErrorResponses.html#ErrorCodeList)
// . For more information about CORS, see Enabling Cross-Origin Resource Sharing (https://docs.aws.amazon.com/AmazonS3/latest/dev/cors.html)
