Which component of the Push Notifications feature stores the messages that are ready to be...

Push Notifications in Oracle APEX enable real-time messaging to users’ devices via Progressive Web App (PWA) capabilities. The component responsible for storing messages is:

A. Queue: ThePush Notification Queue(managed internally by APEX and accessible via APIs like APEX_PWA.PUSH_QUEUE) temporarily holds messages scheduled for delivery. When a notification is created (e.g., via APEX_PWA.SEND), it’s added to this queue, awaiting processing by the APEX mail system or an external push service. The queue ensures reliable delivery, even if the user is offline temporarily, as messages are dispatched once connectivity is restored.

B. Application: The application defines the PWA settings and logic but doesn’t store messages; it’s the container, not the storage mechanism.
