There was an issue with the Undiscord window being transparent and impossible to see. I applied the following fixes: 90e7369, 0a144e7, and 672941b listed on https://github.com/victornpb/undiscord/pull/712. I noticed in 0a144e7 that there was a hashtag here '#undiscord .input' but for some reason it was written as 'undiscord .input' in the userscript. I added the hashtag because that is probably the correct syntax.
