      // In this demo, we are showing how to initialize Web Chat with a secret. This is NOT RECOMMENDED for deployed bots.
      // Your client code must provide either a secret or a token to talk to your bot.
      // Tokens are more secure. To learn about the differences between secrets and tokens
      // and to understand the risks associated with using secrets, visit https://docs.microsoft.com/en-us/azure/bot-service/rest-api/bot-framework-rest-direct-line-3-0-authentication?view=azure-bot-service-4.0

      // The code commented out below exemplifies how to implement the same page while fetching a token from your own token server.
      
      // const res = await fetch('https:YOUR_TOKEN_SERVER.NET/API', { method: 'POST' });
      // const { token } = await res.json();
