How to return value from async coroutine scope such as ViewModelScope to your UI?

Question

I'm trying to retrieve a single entry from the Database and successfully getting the value back in my View Model with the help of viewModelScope, but I want this value to be returned back to the calling function which resides in the fragment so it can be displayed on a TextView.

I tried to return the value the conventional way but it didn't work. So, How Can I return this value from viewModelScope.launch to the calling function?

View Model

fun findbyID(id: Int) {
    viewModelScope.launch {
        val returnedrepo = repo.delete(id)
        Log.e(TAG, returnedrepo.toString())
        // how to return value from here to Fragment
    }
}

Repository

suspend fun findbyID(id: Int): userentity {
    val returneddao = Dao.findbyID(id)
    Log.e(TAG, returneddao.toString())
    return returneddao
}

Thank you Nataraj KR for your Help!

Following is the code that worked for me.

View Model

class ViewModel(application: Application):AndroidViewModel(application) {
val TAG = "ViewModel"
val repo: theRepository
val alldata:LiveData<List<userentity>>
val returnedVal = MutableLiveData<userentity>()
init {
    val getDao = UserRoomDatabase.getDatabase(application).userDao()
    repo = theRepository(getDao)
    alldata = repo.allUsers

}

fun findbyID(id: Int){
    viewModelScope.launch {
       returnedVal.value = repo.findbyID(id)
    }
}

}

Fragment

 override fun onActivityCreated(savedInstanceState: Bundle?) {
    super.onActivityCreated(savedInstanceState)

    val usermodel = ViewModelProvider(this).get(ViewModel::class.java)
    usermodel.alldata.observe(this, Observer {
        Log.e(TAG,usermodel.alldata.value.toString())
    })
    usermodel.returnedVal.observe(this, Observer {
        tv1.text = usermodel.returnedVal.value.toString()
    })

    allData.setOnClickListener {
        tv1.text = usermodel.alldata.value.toString()
    }

    findByID.setOnClickListener {
        usermodel.findbyID(et2.text.toString().toInt())
    }
}
