Good day!
Does any one know if there is interface for Human agent in Microsoft Bot Framework?
I need to forward dialog to real agent in case if visitor can\'
No, there isn't anything built-in for a human to reply as your bot in Bot Framework.
You could make your own interface and hook it up to the Bot Connector via Direct Line
https://docs.botframework.com/en-us/restapi/directline3/
There are samples that solve this specific problem:
I have plans to publish the C# solution as a Nuget package as soon as it gets mature enough, but at the moment you can just copy the code (and modify to suit your needs) from the repo to your project.
Hope this helps!
Cheers, Tomi
