What is Helper.html

Hey @sales1,

You bring up a good point, we’re working to add more information in regard to use Web Isolation.

In the meantime, I was able to speak with our SDK team to clarify some details:

When using registration with Web Isolation on the Web SDK, a helper file is currently needed in order to allow this registration to work between two separate origins (zoom.us and your site). We are working to improve this process but for now you can copy the code from the helper.html file referenced and use that in your project by defining the file on init().

  ZoomMtg.init({
      disableCORP: !window.crossOriginIsolated, // default true
      helper: './helper.html'
      });

I hope that helps! Let me know if you have any questions.

Thanks,
Max
