+    - `isRetry` <Type text="boolean"/>: A boolean value to indicate if the alarm should be retried.
+
   - The `alarm()` handler has guaranteed at-least-once execution and will be retried upon failure using exponential backoff, starting at 2 second delays for up to 6 retries. Retries will be performed if the method fails with an uncaught exception.
 
   - This method can be `async`.
