How to open settings->messages->unknown & spam programmatically?

Question

I know it's possible to open the settings app in Swift. For example:

UIApplication.shared.openURL(URL(string:"App-Prefs:root=General&path=About")!)

I'd like to open settings->messages->unknown & spam. "Messages" opens using "App-Prefs:root=Messages", but I can't find the correct path for unknown & spam. I tried finding the path myself, and I've also searched the web but found only partial lists of settings' paths.

It should be mentioned that I have no intention of uploading my app to the app store.

What's the way to open this entry?

Answer 1

I was using this successfully, App-Prefs:root=MESSAGES to open "Message Settings" and it was working on Beta 1 and Beta 3... But stopped working on BETA 3.

I couldn't find a way to open the "Unknown & Spam" yet...
