I want to delete the Vercel Storage (Postgre). It was created somehow when I created the project, but I never use it.

Now I want to delete it. But I can't find any place to delete it. It is a deadlock everywhere (even ChatGPT， Claude unable to figure it out.......)

Firstly, ChatGPT/Claude/Google Search suggests I can do it directly in Storage tab. But there is no such an option!

Then I go to Neon, in the "Delete Project" it suggests me to go back to Vercel !!

I also check the integration but don't see anything there!
