Delete Adobe Sign agreement with only Free Accounts

I was testing out signing agreements using Adobe Sign with a coworker to see how it would function, but we soon realized that we wouldn't be able to delete any of out agreements because both of us only have free accounts. Our company hasn't ever purchased Adobe Sign so we have no Privacy Admin, all we can do is view our signed test agreements in the Document Cloud and not much else.

Is there a way to delete the agreements with just free Adobe Sign accounts, or will we just have to hide them?
