Availability of HybridOfflineStore

[oonisim]

There is hybrid_offline_store.py which has HybridOfflineStore. However, there is no documentation.

Please advise if this is available to create a feature view from multiple data sources.

The feature_store.yaml below can be loaded into FeatureStore. But not clear how to add Feature Views there.
