📄️ List channels
List notification channels by NRN.
📄️ Create a channel
Create a new notification channel.
📄️ Read a channel
Read a notification channel by its ID.
📄️ Update a channel
Updates a notification channel. A channel's `type` can't change: sending a different one returns `400`.
📄️ Delete a channel
Delete a notification channel. This action cannot be undone. Deleting an agent channel with a platform-managed credential also revokes that credential with your permissions: if you can't revoke it, the request returns `403` and the channel isn't deleted.
