Ionic geofence is not triggering the notification in android and ios

Ionic Framework ionic-v3
1

Past 2 weeks I am trying to build a geofence Apk, When i initialize the plug in it’s showing plug in is ready and i set the geofence
let fence = {
id: ‘69ca1b88-6fbe-4e80-a4d4-ff4d3748acdb’, //any unique ID
latitude: 12.9330951, //center of geofence radius
longitude: 80.243273,
radius: 100, //radius to edge of geofence in meters
transitionType: 3, //see ‘Transition Types’ below
notification: { //notification settings
id: 1, //any unique ID
title: ‘You crossed a fence’, //notification title
text: ‘You just arrived to Gliwice city center.’, //notification body
openAppOnClick: true //open app when notification is tapped
}
}
and i called method this.geofence.addOrUpdate(fence).then(
() => console.log(‘Geofence added’),
(err) => console.log(‘Geofence failed to add’)
);

I got Geofence is added but my problem is i cross the geofence or come in to geofence radius i didn’t get the any notification,
