Access to Server Notifications and Sandbox Server URLs via App Store Connect API

I'm currently trying to automate the process of retrieving app-specific information such as the Server Notifications URL and the Sandbox Server URL via the App Store Connect API.

From what I could gather from the official API documentation, there doesn't seem to be a way to fetch these URLs programmatically.

Can anyone confirm if these pieces of information are accessible via the API currently or if there are plans to expose this in the future?
