docs: Given a data set type and a from date, asynchronously publishes the requested customer support data to the
  specified S3 bucket and notifies the specified SNS topic once the data is available. Returns a unique request
  identifier that can be used to correlate requests with notifications from the SNS topic. Data sets will be
  published in comma-separated values (CSV) format with the file name {data_set_type}_YYYY-MM-DD'T'HH-mm-ss'Z'.csv.
  If a file with the same name already exists (e.g. if the same data set is requested twice), the original file will
  be overwritten by the new file. Requires a Role with an attached permissions policy providing Allow permissions
  for the following actions: s3:PutObject, s3:GetBucketLocation, sns:GetTopicAttributes, sns:Publish,
  iam:GetRolePolicy.
