items not showing in cart in pinia state in vue3

my cart items is not showing in the cart(which is in state using pinia) after adding them using an action from a button in the shop page

my code:

store.js(using pinia)

import { defineStore } from "pinia";
import Products from "../db.json";

export const useCounterStore = defineStore("counter", {
  state: () => ({
    cart: [],
  }),
  actions: {
    addToCart(id) {
      this.cart.push(id)
      console.log("test passed!")
    }
  }
});

shop.vue

<template>
  <div class="shop">
    <h1>shop</h1>
    <div class="products" v-for="item in Products" :key="item.id">
      {{ item.name }} {{ item.price }}$
      <button @click="storeCounter.addToCart(item.id)">Add to Cart</button>
    </div>
  </div>
</template>
<script setup>
import { useCounterStore } from '../stores/counter';
import Products from "../db.json"

const storeCounter = useCounterStore()

</script>

cart.vue

<template>
    <div class="cart">
        <h1>cart</h1>
        <div class="cartitems" v-for="item in storeCounter.cart" :key="item.id">{{ item.name }} {{ item.price }}</div>
    </div>
</template>

<script setup>
import { useCounterStore } from '../stores/counter';
import Products from "../db.json"

const storeCounter = useCounterStore()

</script>

why it is not working for me? i assume i did everything right...

shop.vue is only pushing the id number into the store's cart array

<button @click="storeCounter.addToCart(item.id)">

cart.vue is attempting to display the cart array as if contains full product objects and not just the ids

<div class="cartitems" v-for="item in storeCounter.cart" :key="item.id">
  {{ item.name }} {{ item.price }}
</div>

This can be easily fixed by changing shop.vue to add the full item instead of just item.id

<button @click="storeCounter.addToCart(item)">
