  <h1>Scan a Barcode</h1>
  <button id="scanButton">Start Scanning</button>
 
  <script>
    const { Format, BarcodeScan } = WTN.Barcode;
 
    document.getElementById('scanButton').addEventListener('click', () => {
      BarcodeScan({
        formats: Format.QR_CODE, // optional
        onBarcodeSearch: (value) => {
          console.log('Scanned value:', value);
          alert('Scanned value: ' + value);
