background “blur” and other zoom SDK features needs the JavaScript function **SharedArrayBuffer**

**SharedArrayBuffer** is disabled by default on all browsers for security reasons

to enable **SharedArrayBuffer** you habe to implement “[Cross-Origin Isolation](https://developers.zoom.us/docs/meeting-sdk/web/gallery-view/#implementation-options)”
