About the attached app's

1. The _-foss_*.apk files are the app with Firebase/Google Cloud Messaging (FCM) services removed. Instead, the app uses a foreground service for polling notifications. This consumes more battery.
2. Files without the -foss extension are app builds that use a flexible approach for delivering notifications and include FCM libraries. By default the app uses FCM. If FCM is unavailable (e.g. on GrapheneOS or on Chinese phones) - the app switches to polling and starts a foreground service.
