[firebase_messaging] How to trigger onMessageOpenedApp from a programmatically created notification?

[FeleConvo]

I'm trying to create a notification programmatically that triggers FirebaseMessaging.onMessageOpenedApp but so far I haven't been able to achieve this.

If I send the notification from the server and add the following:

{... "data": {"click_action": "FLUTTER_NOTIFICATION_CLICK", ... } }

the FirebaseMessaging.onMessageOpenedApp listener is called successfully when the notification is tapped, but I haven't been able to create a notification programmatically that is able to do the same even though I've added "click_action": "FLUTTER_NOTIFICATION_CLICK" to the PendingIntent in many ways, like for example:

        intent?.putExtra("click_action", "FLUTTER_NOTIFICATION_CLICK")
        intent?.putExtra("clickAction", "FLUTTER_NOTIFICATION_CLICK")
        intent?.putExtra("data", Bundle().apply {
            putString("click_action", "FLUTTER_NOTIFICATION_CLICK")
            putString("clickAction", "FLUTTER_NOTIFICATION_CLICK")
        })

And many more.

So how can I achieve this? How is this click_action handled by the library?
