While users may not delete an agreement, they can hide them from view allowing the user to thin out the lists of objects on their Manage page.
The below process only removes the agreement from the user's view, it does not delete the agreement from the system (as GDPR tools will do), nor does it remove the agreement from the view of other users that are entitled to see it. A hidden asset is only hidden for the user that hides it.
Unhiding an agreement is relatively easy to do, so users should be comfortable hiding anything that impedes their activities, knowing they can reclaim visibility of those assets as needed.
Unhiding an agreement only requires that you know how to search for it (Agreement name, recipient email) and access to your Adobe Sign Manage page:
Your page should refresh and the agreement is no longer visible.
This is because the agreement is no longer hidden, but your current view has the Hidden Content filter applied.
Click the X on the Hidden content filter to remove it, restoring your view to the unfilterd content of your Manage/Documents page
