```javascript
async function presentAlert() {
const alertController = document.querySelector('ion-alert-controller');
await alertController.componentOnReady();
const alert = await alertController.create({
header: 'Alert',
subHeader: 'Subtitle',
message: 'This is an alert message.',
buttons: ['OK']
});
return await alert.present();
}
