Here is a working demo of the feature using the Twitch RTMP URI.

Note The embedded player will not load when using the Vimeo RTMP URI (Start Free Demo), as the viewing of that event is private and is limited to your viewing only, as seen in the screenshot. In order to broadcast using Vimeo and have that stream be visible to the public, you must subscribe to their premium service. As a result, using the Vimeo Free Demo won't function because the event's viewership isn't public or password-protected.

Please fix the styling of the embedded Twitch stream. It is not responsive and gets overlapped when the chat window is opened.

@VanshulB, thanks for the PR; the component works perfectly fine. It just needs some styling and documentation changes, so once these are rectified we will be good to merge this. Please have a look at the comments. Thank you!

Hello @Dnouv I made the embedded player responsive and corrected the design; for your convenience, I've added a demo video. Please let me know if I made any mistakes.
