Как очистить RecycleAdapter?

Здравствуйте!
Пытаюсь, при нажатии на кнопку сделать повторную загрузку списка, однако метод clear у адаптера не найден, подскажите как очистить список в адаптере?

class TodoAdapter : RecyclerView.Adapter<TodoAdapter.TodoViewHolder>() {

    inner class TodoViewHolder(val binding: ItemTodoBinding) : RecyclerView.ViewHolder(binding.root)

    private val diffCallback = object : DiffUtil.ItemCallback<Todo>() {
        override fun areItemsTheSame(oldItem: Todo, newItem: Todo): Boolean {
            return oldItem.id == newItem.id
        }

        override fun areContentsTheSame(oldItem: Todo, newItem: Todo): Boolean {
            return oldItem == newItem
        }
    }

    private val differ = AsyncListDiffer(this, diffCallback)
    var todos: List<Todo>
    get() = differ.currentList
        set(value) { differ.submitList(value) }

    override fun getItemCount() = todos.size

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): TodoViewHolder {
        return TodoViewHolder(ItemTodoBinding.inflate(
            LayoutInflater.from(parent.context),
            parent,
            false
        ))
    }

    override fun onBindViewHolder(holder: TodoViewHolder, position: Int) {
        holder.binding.apply {
            val todo = todos[position]
