How to use the @google-cloud/vision function in @google-cloud/vision

async resolve({ request }) {
    const { id, imageUrl } = request.body.variables.pin;
    const { userId } = request.body.variables;
    // Let's call Google Machine Vision API
    const vision = new Vision({
      projectId: "ai-concierge-185823",
      keyFilename: config.googley_key_file,
    });
    const minAccuracy = 0.4;
    const req = { source: { imageUri: imageUrl } };
    const visionResponse = await vision.landmarkDetection(req);
    // check if the machine vision has detected a landmark with good accuracy
    const isLandmark = visionResponse[0].landmarkAnnotations.length > 0;
    if (!isLandmark) return { pinId: id, detected: false };
    const bestGuess = visionResponse[0].landmarkAnnotations[0];
    const hasGoodScore = bestGuess.score >= minAccuracy;
    if (!hasGoodScore) return { pinId: id, detected: false };
    // it's good - we can return a detection with all info
    const annotations = visionResponse[0].landmarkAnnotations;
    const goodAnnotations = annotations.filter(
      anno => anno.score > minAccuracy,
