Contributions summary:Xavier implemented and tested regular expression matching for notification subscriptions within the at_client SDK. This involved modifying the notification service to support more flexible key matching using regex. The changes included adding a new utility function to test regex matches and integrating the functionality into the notification service implementation to filter notifications based on defined regex patterns.
