In earlier versions of cordova-plugin-dialogs it was possible to make your custom notification sound as noticed in earlier documentations of the official plugin of cordova cordova-plugin-dialogs.
However, in currect version, I couldn't find any way to change the notification sound of beep function, either in settings of iOS or by adding a custom ´wav´ file in www folder.
Any idea how to change it?
The earlier documentation only allowed a custom sound for Android as it had no default beep sound. There was no override for iOS. I guess since then, Android got its default sound. You couldn't change it for iOS and now you can't for Android too.
