Cal function from another class/interface

Hello guys)
I using ROOM request-function inside my ViewModel class(like a “ClearData”). Help me please transfer my function “ClearData” to another class/interface and just call it from ViewModel class.

class TitleViewModel( val databasedao: CountDataBaseDao, application: Application): AndroidViewModel(application) {

//here different code

   //This function i need to call from another place, i should manage this function at another place and here just call it

    fun clearData(){
        viewModelScope.launch {
        databasedao.clear()
        }
        _count.value=0
    }


}

what i want - something like that :

class TitleViewModel( val databasedao: CountDataBaseDao, application: Application): AndroidViewModel(application), WorkWithDataBase {

fun clear(){
               clearDataWork()} //but i cant just call this function - interface want make me override this fun
}

My interface which contains function clearDataWork()

 interface WorkWithDataBase {


 fun clearDataWork(count: MutableLiveData<Int>,dataSource: CountDataBaseDao){
        GlobalScope.launch {
            dataSource.clear()
        }
        count.value=0
    }
}

Totally i want recode my project https://github.com/bboykot/myRepo to more SOLID (transfer dataBase functions to one place and call it in my ViewModels classes).
Help please.

Problem solved.
