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
}

LiveData can be used to get value from ViewModel to Fragment.

Make the function findbyID return LiveData and observe it in the fragment.

Function in ViewModel

fun findbyID(id: Int): LiveData</*your data type*/> {
    val result = MutableLiveData</*your data type*/>()
    viewModelScope.launch {
       val returnedrepo = repo.delete(id)
       result.postValue(returnedrepo)
    }
    return result.
}

Observer in Fragment

findbyId.observer(viewLifeCycleOwner, Observer { returnedrepo ->
   /* logic to set the textview */
})
