Is it possible to add an image icon to FCM notification in android / iOS?

Question

Is it possible to add an image as icon in the notification tray using the java firebase API? I have a spring boot backend and this is how I build the AndroidConfig:

    private AndroidConfig getAndroidConfig(String topic) {
        return AndroidConfig.builder()
            .putData("image", "url-to-image")
            .setTtl(Duration.ofMinutes(2).toMillis()).setCollapseKey(topic)
            .setPriority(AndroidConfig.Priority.HIGH)
            .setNotification(AndroidNotification.builder().setSound("default")
                .setColor("#FFFF00").setTag(topic).build()).build();
    }

but there is no image here in the notification tray:

Is it even possible to do this with the java API?

Looking at AndroidNotification.builder it has a setImage method ( https://firebase.google.com/docs/reference/admin/java/reference/com/google/firebase/messaging/AndroidNotification.Builder.html#setImage(java.lang.String) that should do the trick.

I've only created FCM notifications in node, but the notification builder looks similar to the payload I send in node to include images.
