Follow-up: Programmatically detecting "Allow in Private Browsing" for Safari App Extensions

I am following up on Thread (https://developer.apple.com/forums/thread/733233). Currently, SFSafariExtensionManager.getStateOfSafariExtension only returns if an extension is enabled, but not if "Allow in Private Browsing" is toggled on.

Is there an API in macOS 26 and Safari 19 that allows a native Safari App Extension to detect this specific permission?
