Ably Core extension - push notifications

Hello Xano Community,
I am having trouble understanding how to implement push notifications via the Ably Core extension. Does anyone have experience implementing this feature in Xano?

Currently, I have followed Ably's tutorial for setting up iOS push notifications, have received the necessary apple certifications and configured my Ably App on Ably's site. However, I am getting stuck on the section in implementing code as I am solely using Xano's /ably/push API provided in the Ably Core extension. How would I proceed in implementing push notifications through Xano and Ably?
