Unable to delete uploaded documents

[AnselmJeong]

I am satisfied with the quality of summaries and other Q&As more than any other service. However, I am concerned that I cannot find a way to delete a document once it's uploaded. Wouldn't that mean documents will just keep accumulating? From the user's perspective, I'm also worried about private information being leaked.

Since I might not know the way to delete a document, I would appreciate your guidance on how to do it.
