// Returns a list of the access points that are owned by the current account
// that's associated with the specified bucket. You can retrieve up to 1000 access
// points per call. If the specified bucket has more than 1,000 access points (or
// the number specified in maxResults , whichever is less), the response will
// include a continuation token that you can use to list the additional access
// points. All Amazon S3 on Outposts REST API requests for this action require an
// additional parameter of x-amz-outpost-id to be passed with the request. In
// addition, you must use an S3 on Outposts endpoint hostname prefix instead of
// s3-control . For an example of the request syntax for Amazon S3 on Outposts that
// uses the S3 on Outposts endpoint hostname prefix and the x-amz-outpost-id
// derived by using the access point ARN, see the Examples (https://docs.aws.amazon.com/AmazonS3/latest/API/API_control_GetAccessPoint.html#API_control_GetAccessPoint_Examples)
// section. The following actions are related to ListAccessPoints :
//   - CreateAccessPoint (https://docs.aws.amazon.com/AmazonS3/latest/API/API_control_CreateAccessPoint.html)
//   - DeleteAccessPoint (https://docs.aws.amazon.com/AmazonS3/latest/API/API_control_DeleteAccessPoint.html)
