I did not find any section or element, which would be pure <insert code>. I have a beautiful 3D images in http://app.tripbeen.com/bruno-4/at-home-in-prague-21 and there is an option to embed them into any website.
I can only insert some other components and then replace a code (icon on the right side), but everything disappears. I probably deleted some important part of the code.
I want just embed for example this code:
<!-- Start Embed Map -->
<div style="margin:auto;width:100%;max-width:800px">
<iframe src="http://app.tripbeen.com/embed-photo360/4-4d504720398b48177e9ed12aba13212f+originals+59454b2db63d6a6ef8753413c2b870cd?fr=fr_cfd09&ratio=0.8"
id="fr_cfd09" frameborder="0" width="100%"

</iframe>
<script>
(function(){
var i='fr_cfd09', f=document.getElementById(i), j=document.getElementById(i+'_w');
window.addEventListener('message', function(m){
var d=m.data;
if (d.t==='r' && d.i===i) {f.height=d.v+'px'}
else if (d.t==='v') {
j.classList.add('open');
setTimeout(()=>{j.contentWindow.postMessage({i:d.i,v:d.v},'*');},10);
}
else if (d.t==='x') {j.classList.remove('open');}
}, false);
}())
</script>
</div>
<style>
.tb-fs-mw{position:fixed;left:0;top:0;width:100%;height:100%;display:none;background:black;}
.tb-fs-mw.open{display:block !important;}
</style>
