Need to delete a signed document that was uploaded to adobefreeuserschannel

I used AdobeAcrobat Reader DC to fill out and sign a document.  After I was done, it asked how I wanted to send the document, etc. And I said to create a link.

Unfortunately, this link is accessible to anyone who has the link and now I have a document with sensitive personal infomation that anyone can accesss without a password.

It was uploaded to adobefreeuserschannel.na.documets.adobe.com

How can I delete this?
