Subpath for access to Silence Unknown Callers

Hi,

Our app has a section where, we show to users how to activate "Silence Unknown Callers", because is a crucial feature for our app. But, we saw that 30% of users drop the process here, because we can't open directly that setting option in phone app.

We are using this url scheme to open phone settings in iOS 18:

if let url = URL(string: "App-prefs:com.apple.mobilephone") {
 
UIApplication.shared.open(url)
 
}

But, we don't see other way to open directly the path "silence", like in iOS 17, with this url scheme: prefs:root=Phone&path=SILENCE_CALLS

So, do you know if is possible open that option directly? We want to improve our accessibility.

Thank you!
