Managing Data Access and Tracking Changes

It will depend on the user's permissions. However, there are features such as “Hide confidential data,” “Read-only lock,” or “Editable after submission,” which apply to users with “Reviewer Basic” permissions or lower. These features restrict how users can view or edit the data.
Any changes made to the data are automatically recorded in the “Changelog,” which appears on the right-hand side of the screen. The changelog cannot be edited and helps track modifications, indicating who made the change, when it was made, and what was changed.
