Please describe the bug

I've been working with createBrowserWebSpeechPonyfillFactory and also tested createCognitiveServicesSpeechServicesPonyfillFactory. My project involves integrating an Azure chatbot with WebChat using Direct Line speech. While the speech recognition and response functionalities are operating correctly, I'm encountering an issue with microphone permissions. Each time the microphone button is clicked, the browser (tested on Edge, Chrome, and Brave) prompts for microphone access. Ideally, this permission should be requested just once and not repeatedly with every message.

Here is my entire code

<!DOCTYPE html>
<html lang="en-US">
  <head>
    <title>Web Chat: Browser-supported speech</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />

      }

      body {
        margin: 0;
      }

      #webchat {
        height: 100%;
        width: 100%;
      }
    </style>
  </head>
  <body>
    <div id="webchat" role="main"></div>
    <script>
      (async function() {
        const res = await fetch('https://webchat-mockbot.azurewebsites.net/directline/token', { method: 'POST' });
        const { token } = await res.json();
        window.WebChat.renderWebChat(
          {
            directLine: window.WebChat.createDirectLine({ token:'MYVALUE' }),
            webSpeechPonyfillFactory: window.WebChat.createBrowserWebSpeechPonyfillFactory()
          },
          document.getElementById('webchat')
        );

        document.querySelector('#webchat > *').focus();
      })().catch(err => console.error(err));
    </script>
  </body>
</html>

Do you see any errors in console log?

It should ask for microphone permission at the start once and not on each message.
