Feature description

It would be great if you could add support for Unified Push applications, such as Sunup, to enable notification delivery. Thank you! ❤️

Why do you want this feature?

It would improve ease of use for users who wish to avoid Google Play Services and bypass the proprietary Google FCM notification system

Additionally, implementing Unified Push would prevent multiple apps from individually consuming phone resources. Unlike regular polling, which requires each app to wake up the CPU frequently, Unified Push allows apps to share a single, efficient connection for notifications, significantly improving battery life
