NylasConnect.callback()

NylasConnect.callback() is a simplified callback handler that works for both pop-up and inline authentication flows. This is a convenience method that automatically detects the callback type and handles it appropriately.

// Simplified callback handler
const result = await nylasConnect.callback();
// Or with a specific URL
const result = await nylasConnect.callback(customUrl);

You can pass no parameters to the method if you want to handle the callback using the current window location. If you want to use a specific URL, pass it as a parameter.
