docs: // ApproveAssignmentRequest generates a "aws/request.Request" representing the
  // client's request for the ApproveAssignment operation. The "output" return
  // value will be populated with the request's response once the request completes
  // successfully.
  //
  // Use "Send" method on the returned Request to send the API call to the service.
  // the "output" return value is not valid until after Send returns without error.
  //
  // See ApproveAssignment for more information on using the ApproveAssignment
  // API call, and error handling.
  //
  // This method is useful when you want to inject custom logic or configuration
  // into the SDK's request lifecycle. Such as custom headers, or retry logic.
  //
  //
  //    // Example sending a request using the ApproveAssignmentRequest method.
  //    req, resp := client.ApproveAssignmentRequest(params)
  //
  //    err := req.Send()
  //    if err == nil { // resp is now filled
  //        fmt.Println(resp)
  //    }
