Hi Thiemo, I used the embed code from Figma directly in the page and the prototype works in-page. You can see it at the link below. Click on the ‘Prototype’ in the side nav menu then scroll down a bit. Not sure if XD has an embed code anywhere, but you could try pasting that in an HTML embed in webflow. That’s how I’m using the Figma embed code.
Best of luck!
Steve
