It can be very cool if there is way for integration iframe of XD project in Behance project for demonstrating in case.
This is already possible. When you share your prototype, select the “embed” tab in the sharing pop-up. You can copy and paste that link directly into Behance to embed your prototype.
Here’s a quick GIF to show you how to do it: https://twitter.com/elainecchao/status/752566904980582400
