How to handle incoming call when the app is in the killed state. (React Native/Android)

Everything works fine with the app running in the foreground or in background. But i don’t receive any notification about an incoming call when the app is in the killed state. How can I notify the user that a call is coming in? How i can generally handle an incoming call if the app is in killed state?
I’m working on the Android solution via FCM
