Struggling to figure this out. What is the cleanest code to extract all paths from a multi-dimentional array?

Below is my data.

const Pages = [
  {
    path: ['home'],
  },
  {
    path: [''],
    subpages: [
      {
        path: ['about', 'congleton'],
        subpages: [
          {
            path: [ 'about', 'congleton', 'opening' ]
          }
        ]
      }
    ]
  }
]

And this is the expected outcome:

[ ['home'], [''], ['about', 'congleton'], [ 'about', 'congleton', 'opening' ] ]

This is what I have right now, however i'm getting 'home', '' rather than ['home'],[''].

I need to retain these first 2 arrays.

function Path(page) {
  let paths = page.path;
  if (page.subpages) {
    paths = [paths, (page.subpages).reduce((curr, subpage) => [...Path(subpage)], [])];
  }
  return paths;
}

const paths = Pages.reduce((curr, page) => curr.concat(Path(page)), []).flat();

console.log(paths);
