Why do type overrides have to be in types/next-auth.d.ts?

Question 💬

• Why do TypeScript overrides have to be in a types/next-auth.d.ts file?
• Why can't I place them in global.d.ts or any other *.d.ts file that's included in my tsconfig.json?
• Is there some place in this library that references that exact filename (i.e. types/next-auth.d.ts)?

I've tried placing them in global.d.ts and next-auth.d.ts (in the repository root), but I can only ever get it working when my file is named next-auth.d.ts and when it is in a directory named types/.
