Admin preview as driver
Preview as driver lets an authorized admin view the driver dashboard exactly as a chosen driver would, without swapping authentication tokens. The app changes only the viewer context passed into the metric engine so queries respect driver visibility rules.
Exit preview
Use the exit action to return to normal admin viewing. Stay aware that you are seeing masked or scoped data appropriate to that driver, not an admin superset.
Relationship to impersonation
Preview is a read-side lens. Impersonation actually signs the session in as another user and is stricter; see Impersonation.
