How can I mock a Menu item in order to Unit Test a Menu in AndroidStudio (kotlin)?

I have a util object class for Menu:

object MenuUtil{

      fun updateMenuIconTint(menu: Menu, @ColorInt color: Int) {
         menu.forEach{
         it.updateTint(color)
        }  
      }
      fun MenuItem.updateTint(@ColorInt color: Int){
         var icDrawable = DrawableCompact.wrap(icon)
         icDrawable = iconDrawable.mutate()
         DrawableCompat.setTintList(icDrawable, ColorStateList.valueOf(color))
      }
    
    }

How can I mock Menu and MenuItem in order to test those functions in a unit test?

When attempting to do so I am told that Menu is an interface.
