How to use the @grpc/grpc-js.status.DATA_LOSS function in @grpc/grpc-js

it('should return true for retryable errors', () => {
      [
        status.OK,
        status.CANCELLED,
        status.UNKNOWN,
        status.DEADLINE_EXCEEDED,
        status.RESOURCE_EXHAUSTED,
        status.ABORTED,
        status.INTERNAL,
        status.UNAVAILABLE,
        status.DATA_LOSS,
      ].forEach((code: status) => {
        const shouldRetry = retrier.retry({code} as StatusObject);
        assert.strictEqual(shouldRetry, true);
      });
    });
