# Mark Notification Tray Seen

Use `markTraySeen()` to update the tray’s seen timestamp on the server when the user visits the Notification Tray screen.

This method supports global-level read tracking, separate from per-item seen state. Once invoked, future calls to `getNotificationTraySeen()` will return the new `isSeen` value. It is recommended to call this method as soon as the tray UI is opened.
