How to call a method in another module JavaScript?

I have a class with method performing login

LoginPage.js

class loginPage {
  fillCredentials(username, password) {
    cy.get('[id=username]').type(username);
    cy.get('[id=password]').type(password);
    return this;
  }

  clickLogin() {
    cy.contains("Login").click();
  }
}
export default loginPage;

I have another spec file for testing:

login.spec.js

import {fillCredentials,clickLogin} from '../../support/PageObjects/loginPage'

describe('User Onboarding Emails', () => {
  it('Verification email', () => {
    cy.visit('/')
    fillCredentials('username','password')
    clickLogin()
  });
});

However, it is giving an error of

(0 , _loginPage.fillCredentials) is not a function

I know its a wrong way of calling a method. Is there any way I can use the methods without creating an instance of class to access methods
