vue.js – Vuex – How to store store updates under different tabs?

I have a Vue application using Vuex. If two tabs are open, the changes made to the store in one tab are not displayed in the other.

How can I make sure the storage / data of all tabs are synchronized instantly?

const store = new Vuex.Store ({
State: {
Tasks: []
  }
getters: {
tasks: state => state.tasks
}
}

In the model:

calculated: {
tasks: function () {
return this. $ store.getters.tasks
}
}
