To create an embedded video URL, you have to add "/video-player" at the end of the URL of the video.
Let's say you have this link:https://www.berrycast.com/conversations/32eb77e0-5325-5e7e-b161-d6d957540380
To be able to embed it, you would have to use that URL:https://www.berrycast.com/conversations/32eb77e0-5325-5e7e-b161-d6d957540380/video-player
And after that, you can just put that link into an iframe. Here is an example: https://codepen.io/maubut/details/poEWLpB
