elastic4s: extracting information from RequestSuccess[DeleteByQueryResponse]

Question

I have following code:

def delete(id: String) = {
    client.execute {
      deleteByQuery("myIndex", termQuery("id", id))
    }.await
  }

delete(id) match {
                case failure: RequestFailure => complete(StatusCodes.InternalServerError, failure.body.getOrElse("Unknown reason"))
                case success: RequestSuccess[DeleteByQueryResponse] => {
                  complete("I want to put info extracted from results here...")
                }

I observe that inside success object there is a field by name 'result', and it is of type Left[DeleteByQueryResponse].

RequestSuccess has a map method

final def map[V](f: U => V): Response[V] = RequestSuccess(status, body, headers, f(result))

where U is of same type as 'result'.

I am not really sure how to extract all relevant information from 'result'?
