Showing fcm notification message in JSON format wh

问题:

I am using react-native-fcm library for android device. I am getting notification properly when my application is running, but when my application is in the background or killed then I am getting notification data in JSON format similarly in an image I shared here.

componentDidMount() {
        // iOS: show permission prompt for the first call. later just check permission in user settings
        // Android: check permission in user settings
        FCM.requestPermissions().then(()=>console.log('granted')).catch(()=>console.log('notification permission rejected'));
        /*FCM.getFCMToken().then(token => {
            console.log('Token',token)
            // store fcm token in your server
        });*/
        this.notificationListener = FCM.on(FCMEvent.Notification, async(notif) => {
            console.log('FCM notification', notif)
            this.sendRemote(notif)
        });

        // initial notification contains the notification that launchs the app. If user launchs app by clicking banner, the banner notification info will be here rather than through FCM.on event
        // sometimes Android kills activity when app goes to background, and when resume it broadcasts notification before JS is run. You can use FCM.getInitialNotification() to capture those missed events.
        // initial notification will be triggered all the time even when open app by icon so send some action identifier when you send notification
        /*FCM.getInitialNotification().then(notif => {
            console.log('FCM', notif)
            this.sendRemote(notif)
            //console.log('Initial Notification',notif)
        });*/

        FCM.getInitialNotification().then((notif: any) => {
            // for android/ios app killed state
            console.log("ifAny",notif)
            if (notif) {
                console.log("Any",notif)
                // there are two parts of notif. notif.notification contains the notification payload, notif.data contains data payload
            }
        });
    }




sendRemote(notif) {
    var data = notif.fcm.body;
    var title = notif.fcm.title;
    FCM.presentLocalNotification({
        title: 'App Name',
        body: title,
        big_text: title,
        large_icon: 'ic_launcher',
        priority: 'high',
        sound: "default",
        click_action: this.clickActions(notif),
        show_in_foreground: true,
        wake_screen: true,
        local: true,
        param: notif.notify_about,
        paramData: data
    });
}

notify_about:'', fcm:{action:null, body:"{data:'',time:''}", color:null, icon: '', tag:null, title:"Notification title"}

this is my data format which I am sending from the server.

Here I want to show only data body. But when the app is killed or in the background, it shows the complete body in the notification.And Its working fine when the app is running.
