Silent notification in Android

In my app, the file is small size so I'm not sure if a loading indicator is shown in motivation. But when the download is done, the notification appears in Silent Notification. It's bad user experience, as I click download, and it seems nothing happens (while actually the download is done).

I might be missing some obvious settings, is there anything to show in "normal" notification? Or is it something I need to handle manually e.g. using [flutter_local_notifications](https://pub.dev/packages/flutter_local_notifications).
