How can I write a extension function to instantiate a AndroidViewModel in Kotlin?

Somebody wrote two extension function (Code A2) for both Fragment and FragmentActivity to instantiate a ViewModel, it works well, you can see Code A1 and Code A3.

I hope to write two extension function (Code B2) for both Fragment and FragmentActivity to instantiate a AndroidViewModel, you can see Code B1 and Code B3, how can I do? Thanks!

Code A1

class HomeViewModel_A(private val mDBVoiceRepository: DBVoiceRepository) :  ViewModel() {

}

Code A2

inline fun <reified T : ViewModel> Fragment.getViewModel(noinline creator: (() -> T)? = null): T {
    return if (creator == null)
        ViewModelProvider(this).get(T::class.java)
    else
        ViewModelProvider(this, BaseViewModelFactory(creator)).get(T::class.java)
}

inline fun <reified T : ViewModel> FragmentActivity.getViewModel(noinline creator: (() -> T)? = null): T {
    return if (creator == null)
        ViewModelProvider(this).get(T::class.java)
    else
        ViewModelProvider(this, BaseViewModelFactory(creator)).get(T::class.java)
}

Code A3

class FragmentHome : Fragment() {
    private val mHomeViewModel_A by lazy {
        getViewModel {
            HomeViewModel_A(provideRepository(mContext))
        }
    }

}

Code B1

class HomeViewModel_B(application: Application,private val mDBVoiceRepository: DBVoiceRepository) :  AndroidViewModel(application)  {

}

Code B2

?

Code B3

class FragmentHome : Fragment() {
  private val mHomeViewModel_B by lazy {     
       ?      
  }
}
