Failed to connect to a new db under same project other than default

Hi, do you support connecting to multiple dbs under same project? it doesn't look like it at the latest version. google forestore supports multiple dbs under a same project now.

If planned to support it in future, when would that be happening? If I am wrong, please let me know.
Thanks,

Chris

**Failing test unit, Stackblitz demonstrating the problem**

Provide a failing test unit, or create a minimal, complete, and
verifiable example (http://stackoverflow.com/help/mcve) using
StackBlitz (https://stackblitz.com/edit/angular-fire-start).

**Steps to set up and reproduce**
enter a new database name into datbaseURL: Ex) databaseURL: 'https://test.firebaseio.com' (test is name of db)

**Sample data and security rules**

### Expected behavior

What is the expected behavior?
If dabaseURL is put such as databaseURL: 'https://test.firebaseio.com', it should connect to the test database.
### Actual behavior

What is the actual behavior?
it connects to default db currently.

まず、現在の AngularFire/Firebase 統合で databaseURL がどのように使用されているかを追跡し、リクエストの対象が Firestore か Realtime Database かを確認します。報告されたバージョンとデフォルトではないデータベース名を使って動作を再現します。要求されたデータベースへの、文書化およびテスト済みの接続が、デフォルトの接続を変更せずに機能すれば完了です。
