Build a call lobby to control meeting access

The post discusses implementing meeting access control in a Daily chat application. It covers creating a private room and running the demo locally, setting up a lobby for participants to request access, and granting permissions as owners. The code snippets are in React and use Daily methods and events such as `accessState()`, `requestAccess()`, and `updateWaitingParticipant()` to manage meeting access levels. The application allows for more granular control over meeting access, enabling developers to set up different participant permissions levels. The demo app demonstrates how to create a private room, join a call, and request access using the Daily API.
