Blynk app alarm on disconnect

Is the a way I can get a audible alarm from the blink app upon disconnect from the Esp32 vroom. Since my prototype has to do with public safety. I would prefer something similar to a heartbeat disconnect alarm but it needs to be audible on the blynk app. All my research has to do with the esp32 vroom resetting on disconnect or similar. But I need the app to do something on disconnect. What do I search for or what am I looking for. Sorry Im sure I am just not getting the right terminology.

Try FilterBox app.

But within Blynk there is no option for that?

It’s a separate app.
How it works :
When your device went offline you will receive a notification " your device went offline " now go to filterbox and create a new rule that will change the notification sound every time you get this notification using keywords.
