Thank you @tuanphan. Unfortunately this did not help.
An example of the embedded code is:
<canvas data-prodibi='{"id":"8l68zedo71zm62y","width":3520,"height":4656,"widthMode":"aspectRatio","heightMode":"90vh","branding":false,"account":"wjdrijfhout"}'><script>;!function() {if (window.prodibiAsync == null) { var s = document.createElement('script'); s.async = !0; s.src = 'https://max1.prodibicdn.com/libraries/pages/prodibi.embed.2.0.min.js'; document.body.appendChild(s); }window.prodibiAsync = window.prodibiAsync || [];prodibiAsync.push({ type: "settings", settings: { account: "wjdrijfhout" } });}();</script></canvas>
