How to Create Options Menu for RecyclerView in Android using Kotlin?

// this is the Language model class

class RvAdapter(
    private var languageList: List<Language>,
    private var optionsMenuClickListener: OptionsMenuClickListener
) : RecyclerView.Adapter<RvAdapter.ViewHolder>() {

    // create an interface for onClickListener
    // so that we can handle data most effectively in MainActivity.kt
    interface OptionsMenuClickListener {
        fun onOptionsMenuClicked(position: Int)
    }

    // create an inner class with name ViewHolder
    // It takes a view argument, in which pass the generated class of single_item.xml
    // ie SingleItemBinding and in the RecyclerView.ViewHolder(binding.root) pass it like this
    inner class ViewHolder(val binding: SingleItemBinding) : RecyclerView.ViewHolder(binding.root)

    // inside the onCreateViewHolder inflate the view of SingleItemBinding
    // and return new ViewHolder object containing this layout
    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
        val binding = SingleItemBinding.inflate(LayoutInflater.from(parent.context), parent, false)
        return ViewHolder(binding)
    }

    // bind the items with each item of the list languageList which than will be
    // shown in recycler view
    // to keep it simple we are not setting any image data to view
    override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        with(holder){
