Origin Trial Setup Instructions:

1. Navigate to [Origin Trials](https://developer.chrome.com/origintrials/#/trials/active)

2. Select SharedArrayBuffers in non-isolated pages on Desktop platforms

3. Enter the origin of the project — (for local testing one can enter [http://localhost](http://localhost):[PortNumber])

4. Fill out the rest of the form — estimated page views, checkboxes, etc)

5. Retrieve the Token:

6. In the meeting.html or index.html file (depending on your SDK configuration), for the origin trial meta tag, place your origin trial token in that field. See image below for reference. **Note: Even in the most updated Meeting & Video SDKs, put this to fix participant/host video not showing.**
