                console.warn('FCM remote message');
                await CallKeepServiceI.init();
                CallKeepServiceI.displayIncomingCall();
            }
);

You need to manually change RNCallKeepModule.java file after installing node modules. You need to alter the hasPermissions function like this https://github.com/react-native-webrtc/react-native-callkeep/pull/576/files.

After that, in your background message handler you call theese functions before calling RNCallKeep.displayIncmoingCall(cfg) await RNCallKeep.registerPhoneAccount(YOUR_CONFIG)

await RNCallKeep.registerAndroidEvents()

await RNCallKeep.setAvailable(true)
