     try {
       const granted = await PermissionsAndroid.request(
         PermissionsAndroid.PERMISSIONS.CAMERA,
         {
           title: 'Camera Permission',
           message: 'This app needs access to your camera to scan MRZ.',
           buttonNeutral: 'Ask Me Later',
           buttonNegative: 'Cancel',
           buttonPositive: 'OK',
         }
       );
       if (granted === PermissionsAndroid.RESULTS.GRANTED) {
         console.log('You can use the camera');
       } else {
         console.log('Camera permission denied');
       }
     } catch (err) {
       console.warn(err);
     }
