Hi @Hardik1  
Thanks for reaching out, and welcome to our Developer Forum!  
The reason why you are not getting this event is because Ngrok is a we trust and we do not require it to be validated.  
Can you please confirm if you are receiving other events, like meeting.ended that you have added in your app?
