Does Weatherkit have a webhook for push notifications?

I'm implementing PUSH NOTIFICATIONS for an app that uses Weatherkit ("there is a Tornado outside your house, run!")

I enabled the capability, the code in app delegate, tested the push notification with the new apple console. and everything WORKS,

BUT...how can I receive push notifications from Weather kit? do they have a webhook that I can listen to? I cannot find anything in the documentation.

https://developer.apple.com/documentation/weatherkitrestapi/get_api_v1_weatheralert_language_id

or do I need to create a server to call weatherkit every min?

I don't understand how to listen to weather kit for alerts.

thanks
