Don't get me wrong, I have no gripe about content being made for beginners. I bet content made for that beginner-intermediate level is the most popular so it makes sense to produce that kind of content. And even then, I was able to get some nice pointers even when I didn't have time to watch the stream that much, as I said.
You can find the stream on their Youtube channel:

Youtube live streams are typically available immediately after the live stream ends unless the channel owner deletes the video or specifically doesn't want to archive the live stream.
