Hi all. So my org has a pretty big requirement for presentations and lately we’ve switched everything to figma slides.

Now what we wanted to do was mas the public URL of figma slides (the presentation) with our own organizations URL but it seems that there is some sameOrigin error that prevents this from happens and thus prompts the login screen on load. I’m not sure how to fix it and my dev team has also tried most options. Technically the public URL link should be accessible regardless of where it is hosted right or what URL is it masked under. I’m essentially trying to do the below thing: 
 

If I load just the public link that I got from figma slides as it is in incognito (or a browser where I dont have figma logged in) - then the link loads fine

But as soon as I mask it in my own URL, the public link I got from figma slides starts asking for login. (additionally, if I allow cookies on the browser, then the login screen disappears) 

I’ve also tried using the public iframe link that figma slides gives when you click the {share presentation} button but that too is not working. Same problem persists, it asks for a login. My org uses these slides pretty much for a lot of training and education use cases and we want to put all these links, masked in our own url, on our own CRM system for everyone across org to view. Additionally some of these presentations go out to our investors and other third party vendors so that is why we want to mask the URL, make it more reliable and professional  

Thank you so much
