Start by double-checking your CSS on the iframe and its parent containers for height and overflow properties. If that doesn't work, it's probably an interaction limitation with the Figma embed itself. While there are solutions for general iframe scrolling (like iframe-resizer), getting granular scroll events from within a Figma prototype embedded in an iframe seems to be a current limitation or requires a clever workaround that isn't immediately obvious from the documentation.You can also consider if there's a different way to display your Figma content if the scrolling is a critical feature and the iframe is proving to be a blocker.
