How to use the @loopback/authentication.AuthenticationBindings.AUTHENTICATION_STRATEGY_EXTENSION_POINT_NAME function in @loopback/authentication

async function setupBindings2() {
    addExtension(
      app,
      AuthenticationBindings.AUTHENTICATION_STRATEGY_EXTENSION_POINT_NAME,
      PassportBasicAuthProvider,
      {
        namespace:
          AuthenticationBindings.AUTHENTICATION_STRATEGY_EXTENSION_POINT_NAME,
      },
    );

    // used by VerifyFunctionProvider
    app.bind(USERS_REPOSITORY_BINDING_KEY).to(users);

    // the verify function for passport-http
    app
      .bind(VERIFY_FUNCTION_BASIC_AUTHENTICATION_BINDING_KEY)
      .toProvider(VerifyFunctionProvider);

    // used by the Strategy Adapter

async function setupBindings2() {
    addExtension(

      .to(myUserProfileFactory);
