How can i user hilt Inject RepositoryManager for ViewModel(viewmodel creat by invoke)?

this is my RepositoryManager

@Singleton  class RepositoryManager @Inject constructor(private val retrofit: Retrofit) {        fun <T> obtainRetrofitService(serviceClass: Class<T>): T {          return retrofit.create(serviceClass)      }    }    

ViewModel：

class GankViewModel @ViewModelInject constructor() : BaseViewModel() {        @Inject lateinit var repositoryManager: RepositoryManager        fun getGankGirl() {          repositoryManager.obtainRetrofitService(GankApi::class.java)              .getGankGirls()              .subscribeOn(Schedulers.io())              .observeOn(AndroidSchedulers.mainThread())              .subscribeWith(object : BaseObserver<GirlBean>() {                  override fun success(data: GirlBean) {                      showLoading(true)                  }              })      }  }    

Activity:

@AndroidEntryPoint  class GankActivity : BaseActivity<ActivityGankBinding, GankViewModel>() {        override fun init() {          viewModel.getGankGirl()      }    }  

BaseActivity:

abstract class BaseActivity<VB : ViewBinding, VM : BaseViewModel> :RxFragmentActivity(),      IBaseView {      protected lateinit var binding: VB      protected lateinit var viewModel: VM      private val loading: BasePopupView by lazy {          XPopup.Builder(this).asCustom(LoadingSimplePopup(this))      }        @Suppress("UNCHECKED_CAST")      override fun onCreate(savedInstanceState: Bundle?) {          super.onCreate(savedInstanceState)          val type = javaClass.genericSuperclass as ParameterizedType          val modelProvider = ViewModelProvider(this)            val clazz0 = type.actualTypeArguments[0] as Class<VB>          val method = clazz0.getMethod("inflate", LayoutInflater::class.java)          binding = method.invoke(null, layoutInflater) as VB          setContentView(binding.root)            val clazz1 = type.actualTypeArguments[1] as Class<VM>          viewModel = modelProvider.get(clazz1)            init()            viewModel.loadingEvent.observe(this, { isShow ->              if (isShow) showLoading() else dismissLoading()          })      }        abstract fun init()        override fun showLoading() {          if (!loading.isShow) {              loading.show()          }      }        override fun dismissLoading() {          if (loading.isShow) {              loading.dismiss()          }      }    }
