we are using freshchat widget and recently due to some change in validation logic for JWT was done by freshdesk due to which chat stopped working for us, we were getting below error.

{
    "success": false,
    "errorCode": 5,
    "errorMessage": "Invalid user create request"
}

We got to know about it from a manual reports, therefore now we want to add error alerting. i was hopping freshchat widget would be emitting some event which i can handle like 

window.fcWidget.on("error", ()=> {})

but i am not able to find any such event or callback mechanism in documentation.

Please share if you are aware of any way to achieve this
