inject workmanager through koin Android

Question

Hey I am using Koin in my application. I am trying to inject workmanager in my application according to this answer. I did this successfully but I have little bit confused about workManagerFactory()

Module.kt

val workerModule = module {
    // worker definition
    worker { SimpleWorker(get(), get(), get()) }
}

so when startKoin

startKoin {
    androidLogger(Level.ERROR)
    androidContext(appContext)
    modules(
        listOf(
            workerModule
        )
    )
}

Do I need to add wokerModule in modules as well as workManagerFactory()?

startKoin {
            androidLogger(Level.ERROR)
            androidContext(appContext)
            modules(
                listOf(
                    workerModule
                )
            )
            workManagerFactory()
 }

what is the use case workManagerFactory()? Can someone please guide me because I am reading this medium post. Nothing is mention about it. Thanks
