**Description**  
Participants are unable to see or automatically apply a Virtual Background when joining a Zoom Meeting using the **Web Meeting SDK**.

Even though:

- The signature token includes `video_webrtc_mode: 1`

- `updateVirtualBackgroundList()` and `setVirtualBackground()` are executed

Participants do **not** get the Virtual Background applied automatically, and the Virtual Background UI does not appear for them.

I expected the SDK to apply the virtual background programmatically via  
`ZoomMtg.setVirtualBackground({ id: 'background-default' })`,  
but it is completely ignored for participants.

## **Browser Console Error**

**Which Web Meeting SDK version?**

@zoom/meetingsdk: 4.1.0

**Meeting SDK Code Snippets**  
**Init + Join**

```javascript
ZoomMtg.setZoomJSLib(`https://source.zoom.us/${zoomVersion}/lib`, "/av");
ZoomMtg.preLoadWasm();
ZoomMtg.prepareWebSDK();
ZoomMtg.init({
  leaveUrl: directUrl,
  patchJsMedia: true,
  success: joinZoomMeeting
});

```

**Virtual Background Logic**

```javascript
ZoomMtg.updateVirtualBackgroundList({
  vbList: virtualBackgroundLists,
  success: () => {
    ZoomMtg.setVirtualBackground({ id: 'background-default' });
  }
});

```

**To Reproduce(If applicable)**  
Join a Zoom meeting as a participant (role = 0) via Web Meeting SDK

1. SDK loads successfully

2. `updateVirtualBackgroundList()` succeeds

3. `setVirtualBackground()` is executed

4. Participant joins meeting

5. Participant video is still the real camera background

6. No Virtual Background or it Settings appear
