This is not working because you need the SharedArrayBuffer feature for the SDK to work correctly from 1.9.6.

You can get that by:

- either add the origin trial to keep shared array buffer active (but this will ends soon)
- or you setup web isolation on your application

For web isolation, if you’re not able to set it due to 3rd party solution that did not opt in yet, you can use another origin trial as [mentioned here](https://devforum.zoom.us/t/chrome-shared-array-buffer-web-isolation-3rd-solution-integration-coep-credentialless-to-the-rescue/54964)
