 When an event handler is executed, a new span is created to track its performance, and any errors are automatically reported to Sentry while preserving the original error behavior.
 
 <Alert level="info" title="Multiple decorators">
-  Annotating one function with multiple `@OnEvent` decorators is not recommended, as NestJS provides no way for us to determine the triggering event. Therefore, the resulting span name will include all decorated event names.
-  
-  Instead, use one decorator per event name and handle any shared logic through a separate function.
+  If multiple decorators are used, we will collect all event names to determine the span's name.
+  In case you want to map each event to a specific handler, use one decorator per handler and handle any shared logic through a separate function.
