How to use the pino-std-serializers.wrapResponseSerializer function in pino-std-serializers

function serializeIlpReply (res: SerializedIlpResponse): SerializedIlpResponse {
  if (res.raw && res.raw.fulfill) {
    res['ilp-fulfillment'] = res.raw.fulfill.fulfillment.toString('hex')
  }
  if (res.raw && res.raw.reject) {
    res['ilp-reject-code'] = res.raw.reject.code
    res['ilp-reject-message'] = res.raw.reject.message
    res['ilp-reject-triggered-by'] = res.raw.reject.triggeredBy
  }
  return res
}

export const serializers = {
  req: wrapRequestSerializer(serializeIlpPrepare),
  res: wrapResponseSerializer(serializeIlpReply)
}
