Is there a way to embed a Prezi Presentation into a Prezi Design using iframe? Or if not, is there another method I could use?
Yes, if you have a Premium, EDU Pro, or Team subscription that allows IFrame integrations in Prezi Design, you can also embed Prezi Present view page link or any other link. Copy the view link and use this iframe generator to get an iframe code: https://www.iframe-generator.com/
Next, open the Prezi Design project in the editor, click on the 3-dot button in the left-side toolbox and select Iframe. Paste the code. Here’s also a tutorial on using IFrame integration: Using media integrations in Prezi Design – Prezi Support Center
