"aside" settings in app.config.ts won't work anymore

[xarthurx]

I'm migrating from v1 to v4 recently, and there's one issue that has bothered me a lot:

In v1, I can do:

export default defineAppConfig({
  aside: {
  	level: 2,  // <-------- this one
  	collapsed: true,
  	exclude: [],
  },
}

to control the level of navigation on the left-side panel.
In v4, this won't work, and it always shows everything under content folder.

Is there a way to make it happen?
