[notification] are attachment implemented?

I've been struggling for a couple of days trying to add attachment to my notifications but no matter what path i use i see nothing, i found a post on the discord server that said attachment were probably mobile only at the moment but i went to the android source code and I don't find this line ".setStyle(NotificationCompat.BigPictureStyle() .bigPicture(myBitmap))" that, according to android documentation, is the thing that adds the attachment, in this case as a picture, anywhere, maybe it's implemented only on iOS? I don't know.

I would like some clarification on this because the plugin docs only say try on your device to see if it works
