If you want to reset NebulaGraph, you can log out and reconfigure the database.
When the Studio is still connected to a NebulaGraph database, you can click the user profile picture in the upper right corner, and choose Log out. If the Config Server page is displayed on the browser, it means that Studio has successfully disconnected from the NebulaGraph database.
