Documentation for Integration with Azure bot registration

Hi All, I am new to this forum and I am looking for some help with registering my bot through Azure portal and check the communication via Web Chat.

I am using ngrok and my endpoint URL is https://“ip generated with ngrok”/webhook/botframework/webhook

Below is the error I see : 404 Error

“OPTIONS /webhooks/botframework/webhook HTTP/1.1” 404 342 0.001960 “POST /webhooks/botframework/webhook HTTP/1.1” 404 342 0.001995

It will be great if someone can share a document or steps on how to overcome this.

Thanks

botframework channels are not working since rasa 1.0
