# markNotificationsRead

Mark specific notifications read or unread by id. Pass isSeen: true to mark read (clears them from the unread badge) or false to mark unread. notificationIds come from listNotifications. Only your own notifications are affected: a notification id belonging to another user is a silent no-op, never an error. Returns the updated {id, seen} for each row that changed.
