Instance Methods
Objects created with new Notification
have the following instance methods:
notification.show()

HTML5 Notification implementation, simply instantiating a new Notification
does
not immediately show it to the user, you need to call this method before the OS
will display it.
If the notification has been shown before, this method will dismiss the previously shown notification and create a new one with identical properties.
notification.close()
Dismisses the notification.
Playing Sounds
On macOS, you can specify the name of the sound you'd like to play when the
notification is shown. Any of the default sounds (under System Preferences >
Sound) can be used, in addition to custom sound files. Be sure that the sound
file is copied under the app bundle (e.g., YourApp.app/Contents/Resources
),
or one of the following locations:
~/Library/Sounds
/Library/Sounds
/Network/Library/Sounds
/System/Library/Sounds
See the NSSound
docs for more information.
