What steps are needed to access the Root in the setup function of a Vue 3 component?

I recently built a Vue App and incorporated Vuex for state management. Here is how I set up my app initially:

import { createApp } from "vue";
import axios from "axios";
import App from "./App.vue";
import router from "./router";
import store from "./store/index";

axios.defaults.baseURL = "https://localhost:44349";

const app = createApp(App)
  .use(router)
  .use(store)
  .mount("#app");

In one of the components, I attempted to access context.root.$store within the setup() method but found that context.root was undefined.

<script>
import {ref, computed } from "vue";

export default {
  name: "ClientList",

  setup(props, context) {
    
    const clients = ref([]);

    console.log(context);

    const clientOrdersLenght = computed(() => {
      return clients.value.length;
    });


    return { clients, clientOrdersLenght }
  },
  
};
</script>

I intended to access my store using context.root. While researching solutions, most examples referenced Vue 2 with 'vue/composition-api' as an import. What could be causing this issue?

If you want to interact with the store directly, you can do so by including and accessing it in your code.

store.dispatch('myModule/myModuleAction') store.myModule.state.blabla

import {ref, computed } from "vue"";
import store from './store/index'; // incorporate the store

export default {
  name: "ClientList",

  setup(props) {
    
    const clients = ref([]);

    const clientOrdersLength = computed(() => {
      store.dispatch('myAction'); // invoke dispatch
      store.state.myItem // alternatively, access the store's state
      return clients.value.length;
    });

    return { clients, clientOrdersLength }
  },
  
};

Discovering the convenience of using getStore() from vuex to access my store has been a game-changer for me. It's incredibly helpful. However, I anticipate that in the future, either myself or someone else will need to retrieve the $root (vue instance) of the application for certain reasons. This leads me to wonder: how can one obtain the $root (vue instance) of the app within a child component?
