Deeplink seems not working

[harrykc]

Hello, thanks for the great package.

I am sending notification with deep link, with a custom URI when click the notification. one signal also provided this feature, https://documentation.onesignal.com/docs/links

At the moment I am trying send via GCM, and I have checked node-gcm documentation, it should allows to add link parameter to notification, e.g.
message.addNotification('link', 'app://xxxx/123456');

Also, I have checked sendGCM.js and seems missing 'link' parameter for the notification object, please correct me if I am misunderstanding or can be achieved in other way.

For APN, I have not check yet.

So, could you update this package to support link parameter? Thank you.

More information, I tried click_action but not working, and i found this https://stackoverflow.com/questions/63203360/open-deep-link-url-when-click-on-fcm-notification

'link' is work but seems not mention in the document.

My testing code with node-gcm

var gcm = require('../lib/node-gcm');

var message = new gcm.Message();

message.addNotification('title', 'Hello');
message.addNotification('body', 'World');
message.addNotification('link', 'app://xxxx/123456');


//Add your mobile device registration tokens here
var regTokens = [''];
//Replace your developer API key with GCM enabled here
var sender = new gcm.Sender('');

sender.send(message, regTokens, function (err, response) {
    if(err) {
      console.error(err);
    } else {
      console.log(response);
    }
});

link parameter seems not used any more, but it still work for me. So i use node-gcm directly.
