are there web extensions that I can use to view unlisted videos on any given youtube channel

As of my last knowledge update in October 2023, there are no official web extensions or tools that allow users to view unlisted YouTube videos on any given channel without the video's owner sharing the link. Unlisted videos can only be accessed by users who have the specific link, and extensions that claim to provide access to such content would likely violate YouTube's terms of service. If you're interested in viewing unlisted videos, the best approach is to directly ask the content creator for the link. Always respect the creator's choices regarding their content and privacy.
