I've just found out that defineNuxtPlugin, useRouter, and useNuxtApp are auto-imported in Nuxt, so the from 'nuxt/app' line isn't needed. https://nuxt.com/docs/guide/concepts/auto-imports#explicit-imports. What do you think? Should we adapt the example to Nuxt auto-import?

[BeltranBulbarellaDD]

I think both ways are fine. IMO I would prefer to leave it as the IDE considers it a linter error, even thought the application will build just fine. I think it does not hurt and prevents an import from the wrong component in case a developer wants to get rid of the linting issue locally.

Looks good!
