title: Which key to use in Bot.App secret property, one from Direct Line or Web Chat Channel?
body: <p>I have configured a Web Chat Channel and a Direct Line Channel on Azure Bot Service. I am using the web chat control on the client side i.e. on a web page to provide a UI to users. For now I am using the Web chat control as it is i.e. included botchat.js in html served from my local server and also botchat.css which I have modified to give a custom look n feel. </p>
  
  <p>There will be requirement in future where I might have to create a custom build of Web Chat control source code, to reduce the overall size of botchat.js file and do some custom implementation as well. My question is it right way to use the UI for a website. Please share your experience and best practice for the same. Are there any other ways to do UI for Website, because I want to support the flexibility of displaying various types of responses like text, video, hero cards etc. </p>
  
  <p>Also, for now I am passing the secret key in the BotChat.App code, but I am confused which secret key to use, the one from WebChat Channel or DirectLine Channel. </p>
