How to add more button above recycler view and show all recycler item in a new activity

[Programming Times Youtube]

I try my best to explain my query.
I have created a movie streaming app. I have succeeded in adding all data from JSON to android studio using retrofit and I use nested recycler view to show all movie categories under one recycler view.
My current output :https://ibb.co/BG6Qgvf
My query is, how to add more buttons to the recycler view on the top right of each category

in amazon prime app they used cat name with arrow mark and added on click event .

it will take them to another activity where that activity shows the clicked even category inside recycler view
can you tell me how to achieve this. I have tried in StackOverflow unfortunately i did not get answer .

2. query . I have an idea to add multiple recyclers for example , for action movie one recycler next for kids movie another recycler will it cause performance issue? if there is any other workaround other than this complex one
