Native Storage module with Ionic 3 Lazy loading

On my Ionic 3 app has around 10 pages and I have implemented lazy loading feature.Now I have a question where about the Native Storage module.Do I need to import it inside the app.module.ts file or is that ok if I'll import it each and every page's module? What is the recommended way of using it and of course the best practice?

app.module.ts

@NgModule({
  declarations: [
    MyApp,
  ],
  imports: [
      IonicStorageModule.forRoot(),
  ],
