Describe the Bug

Hi,

I tried adding a "not-found.tsx" file inside my "src/app/(app)" folder, but this doesn't seem to work. It still shows me the default 404 NextJS page.

Am I missing something or putting the file in the wrong directory?

Reproduction Steps

Put a "not-found.tsx" file in the "src/app/(app)" folder.
