Android Leanback: How to update nested rows item in RowsSupportFragment

Hi
I am working on AndroidTV app using LenaBack, I have an issue over working with live-data. I am using RowsSupportFragment to show list of categories containing list of movies. Every thing is ok and working, but updating specific item inside content list is not possible!

Here is my question with come code snippet there in [stackoverflow](https://stackoverflow.com/questions/74560121/android-leanback-how-to-update-nested-rows-item-in-rowssupportfragment)

I have checked this repository samples but I can not find any implementation near to my logic!

Begin with the linked Stack Overflow question and the RowsSupportFragment usage described here; no repository file or test is named. Compare that setup with the repository samples and determine whether they can demonstrate updating a nested movie item. Done looks like a repository-grounded answer or sample showing how the update works.
