How to use localStorage on Vuejs3?

Question

I'm a little confused about localStorage and its usage. I have a comonent Statistic.vue which displays modal at the end.

Statistic.vue

<template>
 <p class='modal'>{{numberOfGames}}<p>
<template/>

<script>
export default {
    name: "GameStatistic",
    data() {
       return {
            numberOfGames: localStorage.getItem("NumberOfGames")
       } 
    },
    mounted() {
        //this.$store.commit('checkNumberOfGames')
    },
}
</script>

index.js

export default createStore({
  state: {
    currentGuessIndex: 0,
    isWinner: false
  },
  mutations: {
    checkNumberOfGames(state) {
      if (localStorage.getItem("NumberOfGames") === null) {
          localStorage.setItem("NumberOfGames", 1)
      } else if (state.currentGuessIndex >= 6 || state.isWinner) {
          let counter = localStorage.getItem("NumberOfGames");
          localStorage.setItem("NumberOfGames", parseInt(counter)+1)
      }
    }
  },
  actions: {
  },
  modules: {
  }
})

WordRow.vue

// some stuff
watch: {
   submitted: {
      async handler(submitted) {
           //some stuff
           this.$store.commit('checkNumberOfGames')
   }
}

My problem is that the numberOfGames in Statistic.vue is not showing the correct number, after loading the page it shows the correct value otherwise it leaves 1.

I recommend using the Vue Use library. It has a very good modulus for using local storage with VueX/Pinia in Vue.js 3.
