The Lost Ending Of The Assumption Of Moses

More than 20 years back, I found a copy of the Assumption of Moses that was a partial translation which included the passage from Jude 1 vs 9
Edited - So to be clear, one of the adventures this channel may explore, is whether the copy I remember seeing from 20 years back was just one of the many forgeries out there in the land of ancient texts, or was it a legit copy of a book/manuscript/scroll that has been found and catalogued already.
