How to use the ember-cloud-firestore-adapter/utils/parser.buildRefFromPath function in ember-cloud-firestore-adapter

buildHasManyCollectionRef(store, snapshot, url, relationship) {
    const db = this.firebase.firestore();
    const cardinality = snapshot.type.determineRelationshipType(relationship, store);
    let collectionRef;

    if (cardinality === 'manyToOne') {
      const inverse = snapshot.type.inverseFor(relationship.key, store);
      const collectionName = buildCollectionName(snapshot.modelName);
      const reference = db.collection(collectionName).doc(snapshot.id);

      collectionRef = db.collection(url).where(inverse.name, '==', reference);
    } else if (Object.prototype.hasOwnProperty.call(relationship.options, 'buildReference')) {
      collectionRef = relationship.options.buildReference(db, snapshot.record);
    } else {
      collectionRef = buildRefFromPath(db, url);
    }

    return this.buildQuery(collectionRef, relationship.options, snapshot.record);
  },

buildReference(db) {
          return buildRefFromPath(db, urlNodes.join('/'));
        },
      },

serializeBelongsTo(snapshot, json, relationship) {
    this._super(snapshot, json, relationship);

    if (json[relationship.key]) {
      const collectionName = buildCollectionName(relationship.type);
      const docId = json[relationship.key];
      const path = `${collectionName}/${docId}`;

      json[relationship.key] = buildRefFromPath(this.firebase.firestore(), path);
    }
  },
