How To View Unlised Videos on any Youtube Channel

As of my knowledge cutoff in September 2021, there is no legitimate way to view unpublished or unlisted videos on any YouTube channel.
Unpublished videos are those that have not been made public by the channel owner. They are only accessible to the owner and selected individuals who have been granted permission. There is no way for the general public to view unpublished videos unless the channel owner decides to make them public.
