Hey ccrraaiigg!
Unfortunately, right now it is not possible, but it is something we'd like to explore in the future.
Could you please share what end result you're trying to achieve, and how embed => parent communication would help?
Oh, I have embedded a Miro board into an iFrame in my web app, and I’d like to invoke my web app functions by clicking links in my Miro board content. I‘d like to do this so that the embedded Miro board feels like part of my app. Specifically, I’m using a Miro board to document my app. I’d like to click on links in text in the Miro board, and have my app show additional information.
Thanks again!
