                console.log(res)
            }
        })
</script>

<div id="zmmtg-root"></div>
<div id="aria-notify-area"></div>

Hey @live11,

Thank you for reaching out to the Zoom Developer Forum. Are you able to share a screenshot of the browser console?

I would try removing the zmmtg-root div as that should be inserted by the SDK. If that doesn’t help, try using the Sample Web App as a reference.

Thanks,
Max
