How to use the blinkid-react-native.BlinkIdOverlaySettings function in blinkid-react-native

// to scan any machine readable travel document (passports, visa's and IDs with 
            // machine readable zone), use MrtdRecognizer
            // var mrtdRecognizer = new BlinkIDReactNative.MrtdRecognizer();
            // mrtdRecognizer.returnFullDocumentImage = true;

            // var mrtdSuccessFrameGrabber = new BlinkIDReactNative.SuccessFrameGrabberRecognizer(mrtdRecognizer);

            // BlinkIDRecognizer automatically classifies different document types and scans the data from
            // the supported document
            var blinkIdRecognizer = new BlinkIDReactNative.BlinkIdRecognizer();
            blinkIdRecognizer.returnFullDocumentImage = true;
            blinkIdRecognizer.returnFaceImage = true;

            const scanningResults = await BlinkIDReactNative.BlinkID.scanWithCamera(
                new BlinkIDReactNative.BlinkIdOverlaySettings(),

                licenseKey
            );
