[Plugin: Upload Media by Zip] Cannot upload a zip folder

I’m trying to upload an Excel spreadsheet to a PW protected page.

I created a jZip file and when I go to upload the jZip file it opens and shows different components such as
_rels, docProps, xl

I also tried adding the jZip file to the root directory and inserting a download link. But I get the same – I click the download and it shows those same components.

What am I doing wrong?

Thanks
