WebHook / Callback without Bridge?

I’ve used a Nuki from 2021 with a bridge to receive updates (via Callbacks) from the lock.
Activated like this:

GET http://nuki_ip:8080/callback/add?token=<<token>>&url=callbackUrl

Now i’ve upgraded to a Nuki 4 Pro (which has an “integrated bridge”).

How do i (re-)activate callbacks?! Do i need the “advanced API access”?
