React native remote notification - react-native

Question

I am trying to send a mobile push notification to my android device based on apex trigger, and I didn't see notification banner but in console I can see onNotification event fired and I can see my payload info.
I have followed In react native app react-native-push-notification library, all changes are done as per the document mention here https://www.npmjs.com/package/react-native-push-notification.
updated MobilePushServiceDevice whenever user open the with token and service type
On FCM created the project and follow this document https://firebase.google.com/docs/cloud-messaging/android/client
Salesforce create connected enable push notification added server key
here is react code
const notification = PushNotification.configure({
// (optional) Called when Token is generated (iOS and Android)
onRegister: function (token) {
//Send this token to salesforce
let createPayload = {
ServiceType: getSystemName() == 'Android' ? 'androidGcm' : 'apple',
ConnectionToken: token.token
};
// register device with salesforce
},
// (required) Called when a remote is received or opened, or local notification is opened
onNotification: function (notification) {
console.log("NOTIFICATION:", notification);
notification.finish(PushNotificationIOS.FetchResult.NoData);
},
// (optional) Called when Registered Action is pressed and invokeApp is false, if true onNotification will be called (Android)
onAction: function (notification) {
console.log("ACTION:", notification.action);
console.log("NOTIFICATION:", notification);
// process the action
},
// (optional) Called when the user fails to register for remote notifications. Typically occurs when APNS is having issues, or the device is a simulator. (iOS)
onRegistrationError: function (err) {
console.error(err.message, err);
},
// IOS ONLY (optional): default: all - Permissions to register.
permissions: {
alert: true,
badge: true,
sound: true,
},
visibility: 'public',
// Should the initial notification be popped automatically
// default: true
popInitialNotification: true,
senderID: "1019984307481",
requestPermissions: true,
});
here is my apex code
`Messaging.PushNotification msg = new Messaging.PushNotification();
Map<String, Object> androidPayload = new Map<String, Object>();
Set<String> userSet = new Set<String>();
androidPayload.put('title', idVSnickname.get(cbuId)+' assigned you a task');
androidPayload.put('message', subject);
androidPayload.put('parentId', str[4].trim());
androidPayload.put('id', str[0].trim());
userSet.add(accIdVSuserId.get(accId));
msg.setPayload(androidPayload);
msg.send('Mimit', userSet);`
