AlterTableMigration usage in dbflow v5 - class is not open

[eMZet-zz]

DBFlow Version: 5.0.0-alpha1

What is the intended way to run alter table migration in dbflow 5? How to tie AlterTableMigration to specific migration number and database?

In v4 the idea was to extend base class like so:

@Migration(version = 2, database = AppDatabase.class)
class Migration2 : AlterTableMigration<AModel>(AModel::class.java) {
    override fun onPreMigrate() {
        addColumn(SQLiteType.TEXT, "myColumn")
    }
}

which is not the case now

I keep getting This type is final, so it cannot be inherited from on <AModel> Therfore i can't add columns to my table, how can i do it the proper way? And is there any specific documentation for v5, there is a lot of documentation pages which is like a maze each one doesn't mention the version of dbflow it is documenting
