**Description**  
Sometimes, the recording request modal may not appear. I suspect sometimes that the mediaCapturePermission API may not work in my meeting bot implementation. The bot implementation triggers the `onPreviewPannel` event panel, as shown in the snippet below, but is there a more appropriate way to implement this?

**Browser Console Error**

**Which Web Meeting SDK version?**  
2.15.2

**Meeting SDK Code Snippets**

```auto
ZoomMtg.join({
  ...
  success: () => {
     afterJoin()
  }

function afterJoin() {
  ZoomMtg.inMeetingServiceListener(
    'onPreviewPannel',
    handlePreviewPannel
  );
}
function handlePreviewPannel({preJoin: boolean}) {
  if (boolean === false) {
    console.log('mediaCapturePermission request')
    ZoomMtg.mediaCapturePermission({
       operate: 'request'
       success: () => {
              console.log('mediaCapturePermission success')
       }
       error: ({errorCode, errorMessage}) => {
              console.log('mediaCapturePermission error', errorCode, errorMessage);
       },
    });
  }
}

```

**To Reproduce(If applicable)**  
Steps to reproduce the behavior:

1. turn on “Local Recording” in setting page
2. the host(human) starts a meeting
3. the bot (above snippets) joins the meeting
4. sometimes, the recording request modal doesn’t appear, and just ‘mediaCapturePermission request’ appear in console log but **neither ‘mediaCapturePermission success’ nor ‘mediaCapturePermission error’ don’t appear.**

**Screenshots**  
If applicable, add screenshots to help explain your problem.

**Troubleshooting Routes**
