Handling device Token with “Plugin.FirebasePushNotification”

I installed the plugin written in the title. I'm a little bit confused about the devices token. I'm using this code in MainActivity class for android:

FirebasePushNotificationManager.Initialize(this, true);
CrossFirebasePushNotification.Current.OnTokenRefresh += (s, p) =>
{
System.Diagnostics.Debug.WriteLine($"TOKEN : {p.Token}");
StaticClass.NotificationsToken = p.Token;
};
so I get the token and save it in my static class. But when I set the resettoken to false to run the application normally on the device like this :

FirebasePushNotificationManager.Initialize(this, false);
How do I Get the device token? And is there something that could be called in PCL to save the token for both iOS and Android? Thanks in advance
