Peopletools - 9.58.004 Push Notification Framework on HUB

We are in process of upgrading peopletools from 8.56 to 8.58.004 and FSCM on PUM 34.

I recently read of push notification that has more functionality on new peopletools version-

• Push Notifications: The Push Notification Framework supports
       additional notification channels and user personalization in PeopleTools
       8.58. You can configure existing notifications for delivery across multiple
       channels and send broadcast messages from the PeopleSoft system. For each
       notification type that allows personalization, users can personalize how
       they’d like to be notified: selecting one or more channels for delivery of
       notifications.

I read in the Oracle knowledge document that push notification can be sent even through a peoplecode process
