How do query a firestore collection to find document that meet a certain condition? please find an example of the code below.

import { Firestore, collectionData, collection } from '@angular/fire/firestore';
import { Observable } from 'rxjs';

interface Item {
  name: string,
  ...
};

@Component({
  selector: 'app-root',
  template: `
  <ul>
    <li *ngFor="let item of item$ | async">
      {{ item.name }}
    </li>
  </ul>
  `
})
export class AppComponent {
  item$: Observable<Item[]>;
  constructor(firestore: Firestore) {
    const collection = collection(firestore, 'items');
    this.item$ = collectionData(collection);
  }
}

Thank you guys for helping me with the new query syntax. Still can not believe it is not part of official documentation for such a long time…
