I was so confused at first, wondering why it didn't work I thought we were over this Java stuff lol

In Kotlin you would write it like this I think:

@Database(
    version = 2,
    entities = [
        MyEntity::class,
    ],
    autoMigrations = [
        AutoMigration(from = 1, to = 2)
    ],
    exportSchema = true
)
abstract class ...
