Do I have to call super.onRequestPermissionsResult(requestCode, permissions, grantResults) on RequestPermissionsResult?

I have this piece of code and I am not really sure if I should implement super.onRequestPermissionsResult(requestCode, permissions, grantResults) in the else block. I don't know why it should be needed.

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray) {
        when (requestCode) {
            READ_EXTERNAL_STORAGE_REQUEST_CODE -> {
                if (grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    performAction()
                } else {
                    Toast.makeText(this, "You cancelled the permission", Toast.LENGTH_SHORT).show()
                }
            }

            else -> super.onRequestPermissionsResult(requestCode, permissions, grantResults)
        }
    }

I have seen that there is an implementation for this method in the Activity. What does super.onRequestPermissionsResult(requestCode, permissions, grantResults) do? Is it needed?

currently it isn't necessary, as this method is empty. its only uppon to you for handling perm request result

but still you should keep super call in else statement - in this case and all other similar (overriden empty methods). you never know when Android team/library author introduce some default behavior/callback handle in source code (of Android, AndroidX, custom lib etc.) lib without using @CallSuper annotation
