UPDATE: MY FIXED UNDISCORD VERSION HAS ALWAYS WORKED, BUT I FEEL JADED ABOUT UNDISCORD SO I AM SWITCHING TO DISCRUB.
I am thinking about abandoning Undiscord. It does not sit right with me that the 401 errors have existed for three years and the Undiscord developer doesn't want to do anything about it. So many people have posted possible fixes, and not a single one has been implemented. We can show clear, concrete evidence that for the 401 errors, Undiscord is taking a user's password and plugging that into the Authentications Token box. Why in the world would we be happy with our Discord password being taken and plugged somewhere it does not belong? And the fix is so simple. We can just replace the word "password" with "text" and the 401 errors go away and the script works. Also, in two years, we only got one freaking update, and it was a simple one that someone else made. It had nothing to do with 401 errors.
The following extension seems to be a better alternative to Undiscord. I thought about using it 6-12 months ago, but I am often afraid to try new things. But I'm probably going to switch to it now. It is regularly updated, has a lot of users, has a lot of positive reviews, is available on Chrome Web Store, and seems to do a great job. It probably has more features too. Like mass editing messages instead of removing them, etc.
