Unable to delete folder created through attempting to open a text file in a-Shell

[Majixed]

While trying to save a text file from discord to my files app, I accidentally clicked on the option "Open in a-Shell", resulting in the creation of a directory called Inbox in ~/Documents, in which the text file was there. After I got a pop-up stating that a-Shell could not access the file, I managed to successfully remove the text file from the Inbox directory. Although for some reason I'm unable to delete the Inbox directory itself as it states that I don't have the permissions to do so. I tried using chmod on the directory too, although this didn't work as I don't have permissions for that either. Any advice as to how I can delete this directory would be very much appreciated. Thanks in advance.

As far as I can tell, this directory is created by the system and no one can remove it. What does ls -l tell you?
