How to make a callback to the original parent fragment from the second child fragment?

I currently have the ParentFragment which is opening a ActionSheetFragment and onClick of button from ActionSheetFragment opens another fragment ValidationFragment dismissing the current one.

I want to refresh the contents of the ParentFragment when the ValidationFragment is dismissed. The onResume method of the ParentFragment is not called.

I tried using the callbacks but its only working for two fragments.

I also tried the setFragment and getFragment methods. None of them are working because I have the fragment in middle i.e ActionSheetFragment which is dismissed after opening the ValidationFragment. Can anybody help me solve this?

when calling the ActionSheetFragment from ParentFragment, set the parentFragment as targetFragment

 val actiondialog = ActionSheetFragment.getInstance()
 actiondialog.setTargetFragment(this, 119)
 actiondialog.show(this.fragmentManager, "ActionSheetFragment")

and when the ValidationFragment is being called from ActionSheetFragment, just forward the targetFragment to ValidationFragment like: 

val validationFragment = ValidationFragment.getInstance()
validationFragment.setTargetFragment(targetFragment, 119)
validationFragment.show(this.fragmentManager, "ValidationFragment")
[email protected]()

So, in ParentFragment, you get the activityResult with the same code,

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    when (requestCode) {
        119 ->
            if (resultCode == Activity.RESULT_OK) {
                // DO YOUR REFRESHING CODE HERE.
            }
    }
}
