Hi everyone, I’ve been exploring the new `@ConstructedBy` and `RoomDatabaseConstructor` APIs introduced in Room version `2.7.0-alpha06`. According to the documentation, the `initialize` method of the `RoomDatabaseConstructor` instantiates an implementation of the database. However, there’s also a code snippet provided that shows how `RoomDatabaseConstructor` is used:
```fun createDatabase(): MusicDatabase {
    return Room.inMemoryDatabaseBuilder<MusicDatabase>(
        factory = MusicDatabaseConstructor::initialize
    ).build()
}```
I’m a bit confused here. `initialize` method creates a database instance, and then again the database is created using `Room.databaseBuilder`, which accepts `RoomDatabaseConstructor::initialize` that creates a database instance.
Can someone help me understand how this is supposed to work? Specifically, what should happen inside the `initialize` method of `RoomDatabaseConstructor`? Thanks!
