I made a coroutine to update the value of a variable, but it doesn’t work:

fun findNameById(id: Long): String {
    var name = ""
    viewModelScope.launch(Dispatchers.IO) {
        val result = async { repository.findName(id) }.await()
        name = result
    }
    return name
}

The variable name is never updated, it is always an empty string and I don’t understand why. The function findName works well, I checked it, but the variable name is never updated. Why?
