What can a push notification contain?

A push notification can contain:

• Title — a brief text that attracts the user's attention.
• Main message (body) — details of the notification.
• Icon or image — for visual decoration.
• Actions — buttons for quick reply or navigation.
• Payload — additional parameters that the app can process upon receiving the notification.
• Sound or vibration — to attract attention.

For example, a push notification about a new message may include the title "New Message", the message content, and a "Reply" button.
