How to use useI18n inside a Pinia store ?

[mrleblanc101]

Hi,
How can I use t() from useI18n() from the @nuxt/i18n package inside Pinia to translate a string ?
If I try const { t } = useI18n() inside a setup store, I get this error:

Must be called at the top of a setup function

I don't understand since it says:

1. Must be called at the top, it's the first line.
2. of a setup function, it's a setup store, so I should be able to use composable inside it.

I found a workaround which is:

const nuxtApp = useNuxtApp();
const { t } = nuxtApp.$i18n;

But I'm not sure if it's legit.
Also, maybe it could be documented.

I'm pretty sure you can do something similar with plugins: https://pinia.vuejs.org/core-concepts/plugins.html

Main advantage would be that it's not Nuxt-specific (and imo cleaner but that's debatable I guess).
