Disable Twitch extensions

Extension not showing in list to allow

Hello, I have an odd observation, I am unable to see the "The8BitDrummer Song Suggestions" in the list to add to the allow list. Is there any way to add it manually or have the extension list updated to include it? I have a link for the extension itself for your convenience: https://dashboard.twitch.tv/extensions/vsfl1b1y8rrnb6zdzymojuhzgoowuh-1.0.2
