Currently when you insert live content or iFrames onto your Miro board, understandably only you as the user can see the live content when open is clicked
e.g.

But, when you’re in interactive presentation mode there needs to be a way that you can show that live or iFramed content at the same time to everyone viewing the presentation. e.g. you want to play a YouTube video or show a live website and navigate through it (like you can play videos etc in PowerPoint)
