Where is the hot reloading dev site when using Vite?

I have a Bedrock site setup on example.test with the dev-main version of Sage installed. Steps that work for me:

  1. Run npm install
  2. Run npm run dev
  3. Visit http://example.test
  4. Modify app.css or other theme files
  5. The browser with http://example.test opened has been refreshed with my changes
