CUNY Academic Commons

I cloned a group and site for a class I'm teaching this semester. In the library that was copied over, there are multiple files (PDFs) and a doc. When I click "Edit" on the files, I have the option to delete them. However, when I click "edit" on the doc, there is no way to delete the doc from the group library.

I'm seeing this here -- https://commons.gc.cuny.edu/groups/knowledge-infrastructures-2/library/#/ -- and the doc is called "accounts and passwords." I've edited the doc to remove information, but I would prefer to delete the doc from the library entirely.
