*Nature of notification channels*
A notification channel has the following settings we can set, which then control how notifications through that channel are delivered to the user:
- Importance: Urgent will make a sound and show on the screen. High makes a sound. Medium makes no sound. Low makes no sound and gives no indication that it’s been received.
- Sound: Set any supported sound as the notification tone for the channel.
- Lights: Whether the notification should trigger a hardware notification light.
- Vibration: Whether the notification should vibrate your phone.
Show on lock screen: Decide if a notification should appear on the lock screen.
- Override do not disturb: Decide if a notification should bypass any do not disturb settings for sounds.
