Ionic Framework

Hi Ionic Community

I need to style the <IonTitle>. How could I style it directly?

import { IonContent, IonHeader, IonFooter, IonPage, IonTitle, IonToolbar } from '@ionic/react';
import './Home.css';
/* Theme variables */
import '../theme/variables.css';

const Home: React.FC = () => {
  return (
    <IonPage>

      <IonHeader>
        <IonToolbar color="primary">
          <IonTitle size="large">Header</IonTitle>
        </IonToolbar>
      </IonHeader>

    </IonPage>
  );
};

export default Home;

Thank You
