Improve error handling by creating a function handler for connections on servers that use KY, and use the status key in
the response as the key to success instead of catch. Use catch if an error occurs between the client and server, not
between the server and backend.
Complete the OAuth process by adding a redirect when pressing the login button with the provider. When the button is
pressed, the system will request the authentication URL from the backend, then the user will be redirected.
