Name of Channel for Review — Specify the URL of the channel that you want to be used for the review process. To complete our review of your extension, we require the version under review to be fully functional and live on a Twitch channel page until it is approved. Also, if your extension requires live data to operate, please simulate the necessary data to allow our reviewers to use the full breadth of features offered by your extension."
