Customized Local Notifications on iOS

Hey all,

I know it is very on Android, Is it ever possible to have customized local notifications on iOS?

Or at the very least, I'd like to be able to change the image in the notification.

The unity documentation states that an alertLaungeImage is present and could be set, but this never worked for me: https://docs.unity3d.com/ScriptReference/iOS.LocalNotification-alertLaunchImage.html
