Issue: #857

Docs: https://firebase.google.com/docs/cloud-messaging/ios/live-activity

With this field and this configuration I am able to send LiveActivity start messages:

messaging.Message(
        apns=messaging.APNSConfig(
            live_activity_token=live_activity_token,
            payload=messaging.APNSPayload(
                aps=messaging.Aps(
                    alert=messaging.ApsAlert(
                        title="Live Activity Started",
                        body="Your live activity has been started",
                    ),
                    custom_data = {
                        "input-push-token": 1,
                        "event": "start",
                        "timestamp": int(time.time()),
                        "content-state": {
                            "myAttribute": False
                        },
                        "attributes-type": "LiveActivityAttributes",
                        "attributes": {
                            "myAttribute": False
                        },
                    }
                ),
                headers={
                    "apns-priority": "5",
                },
            ),
        ),
        token=cloud_messaging_token,
    )

Thank you for this!!!

I was able to run a successful "update" event using this code (where token is my device's FCM token, and live_activity_token is the existing live activity's token from pushTokenUpdates), but I was not able to trigger a "start" event. Do you know if there any different/additional params needed from your example?

The pushToStart token is different than the pushToken. Check out Activity.pushToStartTokenUpdates

That worked! As a heads up to anyone testing, I also needed to add apns-push-type and apns-topic to my headers. Very excited for this change!

Hi @plarson, Thank you for your contribution! We appreciate it!
Could you fix the lint errors and add a unit test to cover the new property, please? Thanks!
