Location based notifications

I'm currently working on an app that requires location-based notifications, particularly utilizing geofencing to trigger alerts when a user enters specific areas, such as when a student walks into a college campus. However, I'm curious about the behavior of such notifications when the app is fully terminated and not running in the background.

Does anyone have experience implementing geofencing and location-based notifications in apps that are fully terminated? Are these functionalities still active, or does the app need to be running in the background for them to work properly?

Any insights, experiences, or best practices regarding this matter would be greatly appreciated.

Thank you in advance for your help!
