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 ---

I followed up with you in our other thread, let me know if that helps! > [@No Galary View Option And My Screen Is Black](https://devforum.zoom.us/t/no-galary-view-option-and-my-screen-is-black/56493/5): > > Hey @nizamani987, Thank you for following up on this! Currently, we don’t have a method to change the view that a participant is using automatically. If you would like this feature to be considered for a future release, I recommend posting in the #feature-requests category. When it come to using Gallery View on MacOS, what browser are you using? Please see our section on [Gallery View Browser Support](https://marketplace.zoom.us/docs/sdk/native-sdks/web#:~:text=Internet%20Explorer-,Gallery%20View,-%E2%9C%93) Let me know if that helps. Thanks, Max Max ---
