anyone know how I can use graphql-codegen in my vercel configuration? It hast to run after npm i but before next build...
This is my config so far:

{
  "$schema": "https://openapi.vercel.sh/vercel.json",
  "buildCommand": null,
  "devCommand": null,
  "installCommand": null,
  "framework": "nextjs",
  "outputDirectory": null
}
