You can easily make one or multiple Unlisted documents public in just a few steps.
1. Go to your Publication List.
2. Click “PUBLISH NOW” from the drop down menu of that Unlisted content.
NOTE: Content that is already public cannot be made Unlisted/private, and your content will be live and available for everyone to view.
TIP: You can also do this for multiple documents at a time by adding a checkmark next to the content you want to make public, and then click "PUBLISH" at the top of the page.
