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.

Bắt đầu bằng cách theo dõi cách databaseURL được sử dụng trong tích hợp AngularFire/Firebase hiện tại và xác minh xem yêu cầu nhắm đến Firestore hay Realtime Database. Tái hiện hành vi với các phiên bản được báo cáo và một tên cơ sở dữ liệu không mặc định; được xem là hoàn thành khi kết nối đã được ghi lại và kiểm thử tới cơ sở dữ liệu được yêu cầu hoạt động mà không thay đổi kết nối mặc định.
