Hey @diegoroberto,

When it comes to the headers in that document, you would just want to make sure that they are sent by the HTTP server that you’re using. When developing, this would be the Angular Development server.

When it comes to the Cross Isolation, you can alternatively enabled the SharedArrayBuffer Origin Trial to allow the use of the API without Cross Isolation - until Chrome 96.

Let me know if you have any questions.

Thanks,  
Max

Thanks for the reply, and sorry for keep asking but still can’t totally understand.

Do I have to send the Cross Isolation in all Zoom petition (HTTP Header) from Angular, right?

Also is there a way to know if I’ve created and setted correctly the Origin Trial that created from Chrome?

Hey @diegoroberto,

Not a problem, I’m happy to help! Yes, send the HTTP headers with the Angular pages that your app serves.

You can use the following guide to test if SharedArrayBuffers is available on the page:

Let me know if that helps.

Thanks,
