I need to send push notifications to multiple devices using aws-sns-javascript when I create createPlatformEndpoint I can just add one device token but I need to send notifications to multiple devices like an array token

Create Platform Application

var params = {
  Attributes: {
    'PlatformCredential': 'My API KEY'
  },
  Name: 'dist-ba-dist',
  Platform: 'GCM'
};
sns.createPlatformApplication(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Create Platform Endpoint

var params = {
  PlatformApplicationArn:`data.PlatformApplicationArn` , 
  Token: 'My Device Token',
  CustomUserData: 'STRING_VALUE'
};
sns.createPlatformEndpoint(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Sends a message to an Amazon SNS topic

var payload = {
    default: 'Hello World',
    GCM: {
        notification: {
            body: "Sample message",
            title: "Hello World"
        }
    }
};
console.log("endpointArn", data.EndpointArn)
payload.GCM = JSON.stringify(payload.GCM);
payload = JSON.stringify(payload);
console.log('payload', payload)

console.log('sending push');
sns.publish({
    Message: payload,
    MessageStructure: 'json',
    TargetArn: data.EndpointArn,
}, function (err, data) {
    if (err) {
        console.log(err.stack);
        return;
    }

    console.log('push sent');
    console.log(data);
});
