State doesn't seem to be persisted using Nuxt 2 and `secure-ls` package

[theolavaux]

Describe the bug
I'm using Nuxt 2 and I would like to persist my state using the secure-ls package.
If I put log in getItem, setItem or removeItem, none seems to be called.
And my state is not persisted after a page refresh for instance.

To Reproduce
Reproduction link

Steps to reproduce the behavior:

1. Create a Nuxt 2 project.
2. Implement basic Pinia state.
3. Install pinia-plugin-persistedstate2.
4. Create a file named pinia.client.ts with the following content.

import { Plugin } from '@nuxt/types';
import { createPersistedStatePlugin } from 'pinia-plugin-persistedstate-2';
import SecureLS from 'secure-ls';

const piniaPersistedStatePlugin = () => {
  const ls = new SecureLS({ isCompression: false });

  createPersistedStatePlugin({
    storage: {
      getItem: (key) => ls.get(key),
      setItem: (key, value) => ls.set(key, value),
      removeItem: (key) => ls.remove(key),
    },
  });
};

const piniaPlugin: Plugin = ({ $pinia }) => {
  $pinia.use(piniaPersistedStatePlugin);
};

export default piniaPlugin;

Expected behavior
State is persisted
