Display QR Code in e-mail after submit contact form

[liveweb22]

I also have a problem with generating a qr code. I use Contact Form 7 together with Flamingo to generate a QR code. This QR code is generated in the browser, but I don't know how to make it appear in e-mail.

My code:

<script src="https://cdn.jsdelivr.net/gh/davidshimjs/qrcodejs@master/qrcode.js"></script> <script type="text/javascript"> var wpcf7Elm = document.querySelector( '.wpcf7' ); wpcf7Elm.addEventListener( 'wpcf7mailsent', function( event ) { setTimeout(function() { var respElem= document.querySelector( '.wpcf7-response-output' ); var resp = respElem.innerHTML.split("%%"); respElem.innerHTML = resp[0]; new QRCode(document.getElementById("qrcode"), resp[1] ); }, 100); }, false ); </script>

In 3rd tab i have: %%[_date]-[_serial_number]
