Project description:
"The goal of this project is to ensure that incoming call-type notifications (similar to Amazon's RING) triggered by Firebase Cloud Messaging (FCM) are visible on any mobile device, regardless of manufacturer or condition. The notification must be displayed under all scenarios, including:
- When the phone is locked.
- When the app is in the foreground.
- When the app is closed.
- When the screen is off.

The expected outcome is a reliable solution where notifications are consistently visible under any condition across all devices." (client-provided description)
