Hi,
My node.js server endpoint “/” returns an HTML which is represents my Zoom App in Meeting Client. I would like to know if it’s possible to contain jQuery and other JavaScript scripts in the HTML file to execute JS?
When I access the page through web browser, jQuery functionalities work, but they don’t when I start the Zoom App in the Zoom Client.
Thanks.

You might want to make sure that you are including jquery in the [OWASP security headers](https://marketplace.zoom.us/docs/zoom-apps/publishing-an-app/owasp/). If you are are hotlinking from a CDN, I would recommend downloading the jquery library and setting the Content-Security-Policy header to `self`.
