Deep link to Accessibility->Personal Voice

My app speaks and offers the user the ability to use their Personal Voice - but if the user says "No" when I first ask them for permission to use their Personal Voice, I can never ask them again.

So if they change their mind later - they have to go to Settings->Accessibility->Personal Voice to toggle the permission for my app. To make things easier for them, I would like to be able to pop open that page for them - but I don't know how to create the URL for it. Is it even possible?

The closest I've been able to get is to open the settings page for my app (Settings->My App Settings) with:

guard let settingsUrl = URL(string: UIApplication.openSettingsURLString) else {return }

if UIApplication.shared.canOpenURL(settingsUrl) {
    UIApplication.shared.open(settingsUrl)
}

Thanks in advance!
