Pass airtable data to custom block code using fillout form

@acjnas document.write is not the right way to inject I would rather have a container div element and then append iframe into that div via the following code like snippet

<div id="targetDiv"></div>
<script>
        // Select the div where you want to insert the iframe
        var targetDiv = document.getElementById('targetDiv');

        // Create the iframe element
        var iframe = document.createElement('iframe');

        // Set the attributes for the iframe
        iframe.setAttribute('src', 'https://www.example.com');
        iframe.setAttribute('width', '600');
        iframe.setAttribute('height', '400');
        iframe.setAttribute('frameborder', '0'); // Optional: Set to 0 for no border
        iframe.setAttribute('allowfullscreen', 'true'); // Optional: Allow full screen

        // Append the iframe to the selected div
        targetDiv.appendChild(iframe);
    </script>
