Issue with zoom web sdk registrants

I am using an iframe in order to join an meeting and only registered users can join the meeting, I am using this code

<iframe
          allow="microphone; camera"
          style={{
            border: "0",
            height: "100%",
            left: "0",
            position: "absolute",
            top: "0",
            width: "100%",
          }}
          src={`https://success.zoom.us/wc/join/${91282050654}`}
          frameBorder="0"></iframe>

once I click on join button it is redirected to register user page.
what I want is if the user is registered for the meeting then he should directly join the meeting by skipping that registration form

Hey @akash1,

Thank you for reaching out to the Zoom Developer Forum. It looks like you’re attempting to display the Web Client within an iframe which isn’t supported by our Web Client or the Web SDK.

If you are looking to embed Zoom in your website, you’ll want to follow our guide on the Web SDK and review our Sample Web App to implement the SDK directly within your application.

Let me know if that helps.

Thanks,
Max
