// considered in-progress or pending and the response includes HTTP status code 202
// with an invocation request ID, indicating that the client should commence
// polling for the result using the invocation request ID. Access to this endpoint

// capability to provide updates on the progress of the request, contingent upon
// the workload's provision of such information. In-progress responses are returned
// in order. If no in-progress response is received during polling you will receive
// the most recent in-progress response. Only the first 256 unread in-progress
