What does the variable format "${variable}" signify in custom notifications?

The variable format "${variable}" signifies dynamic field references in custom notifications. This syntax allows you to insert specific values that can change based on the context of the notification being generated. By using this format, you can dynamically include information such as user details, event specifics, or other relevant data that is pertinent at the time the notification is created. This enhances the relevance of the message sent to users, making the notifications more informative and tailored to specific situations.

Dynamic field references help automate the notification process by ensuring that the content is automatically populated with the latest available information, streamlining communication and reducing manual input error. This feature is particularly useful in systems that require real-time updates and personalized messages, as it inherently adapts to the variables present at the time of notification.
