1. Import package
2. Add id='veryfi-container' to container you want lens to appear
3. Add id='blur-detector' to edit screen if you want to use it's logic
4. Create following function

const startLens = async () => {
      veryfiLens.setUserAgent(navigator.userAgent); //might not be needed if navigator is availible before the sdk
      veryfiLens.setLocation('US') // 'US' or 'Brazil' to choose servers
      veryfiLens.init(sessionToken);
      veryfiLens.startCamera();
      intervalRef = window.setInterval(() => {
        setSocketStatusColor(veryfiLens.getSocketStatusColor()); //if you want to see socket status
      }, INTERVAL);
    };

5. Call it
6. Use the following on capture button

const takePhoto = () => {
    veryfiLens.capture(setImage, setIsEditing);
  };  
where setImage is a setter for cropped image that you will use further and setIsEdiditing is a setter for isEditing that would typically be used to change from camera screen to editing(screen with cropped image)
