Good Day, @nizamani987,

Welcome to the Developer Forum – I am thrilled to help out here. As a start, please make sure that you are running in Web Isolation or using the Origin Trial. Down below I’ve linked a helpful developer forum post along with our Web Isolation documentation for reference:

> [@Gallery View Button not showing in Chrome Browser](https://devforum.zoom.us/t/gallery-view-button-not-showing-in-chrome-browser/54674/3):
>
> Is your app running in Web Isolation or using the SharedArrayBuffer Origin Trial? That looks like one of the features that get disabled when the SDK has no access to the SharedArrayBuffer, which is no longer accessible in the latest Chrome update unless running in Web Isolation or using the Origin Trial. For reference:

Web Isolation documentation:  
[https://marketplace.zoom.us/docs/sdk/native-sdks/web/advanced/web-isolation](https://marketplace.zoom.us/docs/sdk/native-sdks/web/advanced/web-isolation)

Please check those resources out and let me know if this helps.

Best,  
Donte
