Please clarify following points:
- Can we restrict a user to inter the meeting room only once. In other words, a user logged in from a device should not be allowed to login from any other device.
- How can we hide the URL from end user so that they can not temper the query string?
- How can we open the zoom.us URL in a iframe?
- Can we create a taken based login. The token should be disabled/expired as soon as it is used for first successful login.
