Critical Alerts
An entitlement that permits an app to receive critical alert notifications.
Discussion
If your app has this entitlement, then it can request criticalAlert authorization to receive push notifications that cause the system to play a sound even when the app is locked, muted, or a person uses Do Not Disturb focus. Your app can specify a custom sound and volume for critical alerts.
To request this entitlement for your app, fill out the request form.
