In DLP Policy, under Agent Configuration, you have a tab called Security. There you can add users for manual tagging. Once you have the right to do Manual tagging, you can right click on a file and the "Manual Tagging" button appears.
Make sure to apply the new policy after you add you user to the security tab, and also sync the pc you're on.
If I setting that alreaady, the client still not show "Manual Tagging", is somewhere should check it?
I tried some times but not see "Manual Tagging" Button. How to troubleshoot? Thanks!
