In order for your payers to be able to view and access the live YouTube Live comments section, they'll need to go to YouTube to watch the video instead of watching the embedded video. In order to do that, you can just paste the URL for your video in the Product Description section. Your payers will be able to click the link to access the comments section and the video. If you’d prefer to link text, place a square bracket around the text followed by a web address in parenthesis.
For example:
[Click here](http://www.example.com) to view.
