You can test out this extension right away!

1. Go to the Firebase console and navigate to your Firestore dashboard.

2. If it doesn't already exist, create the collection you specified during installation: ${param:NOTIFICATION_COLLECTION}.

3. Add a document that has a notification top level field with title and body inner fields, and either a deviceTokens or topic top level field:

{
    deviceTokens: ['deviceToken1', 'deviceToken2'],
    notification: {
        title: 'Order Update!',
        body: 'Your order has moved to processing.',
    }
}

or

{
    topic: 'mytopic',
    notification: {
        title: 'Update our App!',
        body: 'A new version of our App is availiable.',
    }
}

1. In a few seconds, a notification will appear on the corresponding devices.

The notification is a top level field that determines what content your notification payload will have. It has two required inner fields:

• title The title of the notification that will be displayed on your devices platform
• body The body or main content of the notification.

The deviceTokens field is a top level field that is an array of strings that contain the device tokens of each device where you want the notification to be sent to. If you only want a single device to recieve a notification, then you would only have one element in the array. This field cannot be used with the topic field.

The topic field is a top level field that is the name of a topic in your Firebase Cloud Messaging instance that has registered devices. You can only put one topic in this field, if you wish to send to multiple topics, you must create multiple documents in the collection. This field cannot be used with the deviceTokens field.
