I want to make routes that look like this,

example.com/parentCategory/newsId
example.com/parentCategory/category/newsId


so, parentCategory, category, newsId these are dynamic.

I went with

app/
   [parent_slug]
     - page.tsx
     - [child_slug]
         - page.tsx
     - [details_slug]
         - page.tsx

Now, how could I show the details slug in the parent slug or child slug?

Thanks for your help.
