useAuthUi()allows you to control the display of the Auth UI modal within the AuthUiProvider. This is the recommended way to handle sign-in to Auth. The hook exposes the following methods and variables to manage the modal’s behavior. 
Page.tsx

const { openLogin, closeLogin, isLoginOpen } = useAuthUi();

UseAuthUi Methods

​
openLogin()

Method that presents the modal to connect with the sign-in options provided by this library. Example: 
const { openLogin } = useAuthUi();
...

return (
  <div className={styles.page}>
  ...
  // Your UI logic goes here		
    {!userSession && (
      <button
        className="custom-button"
        onClick={() => openLogin()}
      >
        Sign In
      </button>
   )}
  ...
 );

​
closeLogin()

Method to close the modal. It provides a pragmatic way for developers to implement complementary logic to close the modal in their applications. When the login process is completed, this method is automatically called and sets isLoginOpen to false.

​
isLoginOpen

Boolean that can be used to validate conditionals and/or manage other UI components if the modal is open or closed. It turns true when the modal is open and false when the Modal closes. Example: 
const { isLoginOpen } = useAuthUi();
...

if (isLoginOpen){
// Your validation logic goes here
}

...

{ isLoginOpen (
// Your conditional UI logic goes here
)
