Docs I'm using: https://vercel.com/docs/workflow-collaboration/vercel-toolbar/in-production-and-localhost/add-to-localhost

Problem: The main goal here is to enable feature flags in production.

As a first attempt, I'm trying to see if I can enable it in local development -- before production.

What I've already completed:
1. npm install
2. vercel link
3. configured next.config.mjs (mine is not next.config.js)
4. add VercelToolbar to my layout.tsx
