 * Retrieves messages between the business and participant.

 * Up to 30 messages are returned per request. If the number of messages in a conversation is larger than 30,
 * `pagingMetadata.cursors` is returned in the response, indicating that another page of results is available.
 * To retrieve the next page of messages, pass the `next` cursor value
 * in the next request's `paging.cursor` parameter.
 *
 * To ensure you'll always retrieve the next record,
 * use the same visibility and sorting
 * in the first request and all subsequent requests.
 *
 * By default,
 * 30 messages are retrieved and sorted by `sequence` in descending order
 * (the most recent messages are first in the list).
