Enabling Extensions via the iframe embed

How do you enable the extensions to work through the embedded iframe? I can see that they work if you then click the “pop-out viewer” but is it possible to enable them via the main embed? I was expecting it to be a JS configuration setting of some sort

Extensions only work on the native Twitch Page.
Using the popout opens the Twitch Website, giving the required context for Extensions to function.

So long story short: You can’t.

Ah okay. That’s a bit poor as being an iframe the content is running from their server and could load everything in that it’d need. I’ll have to look for an alternative then.
