Add Add Button UI to a turning page book (1 UI for page)

I have a prefab for a book that flips its pages. I want to have each page have a button that loads a different scene. The name of the Prefab is “Book-Page Curl” found in the FREE Assets store in Unity, but for what I can see, each page is a Sprite and does not show in the Preview panel. Can I add a Button UI to each page of this book? Thank you for your time.

From what I see this asset works by switching the images of the objects, but the objects remain the same. Try adding a button as a child of one of those objects:
![1]
and observe the results. Later, you can set duplicates of the same button ( calling the same function) as children of each of those objects and just switch them on/off by subscribing to OnFlip event in Book.cs
