**Description**  
We tried out virtual background feature using video sdk, but “isSupportVirtualBackground” always return false and other methods like “addVirtualBackgroundItem” always return nil.

Is there any other prerequisite settings or initialization procedures to enable this feature? Since guidance is not written on doc, it is extremely difficult to use this feature.

Also, a similar problem is occurring on Android too.

Thank you

**Which iOS Video SDK version?**  
1.6.2

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

1. Just call “isSupportVirtualBackground” before or after connecting to a room

**Smartphone (please complete the following information):**

- Device: iPhone13 mini
- OS: iOS15.5

Hey @koudai.kikuchi,

In order for Virtual background to work, you will need to add the zoomcml.xcframework into your project with “Embed & Sign”. You can find this file under the downloaded Video SDK zip file through our marketplace link by navigating to through Sample-Libs \> lib.

Thank you.

Cheers!
