How can I change store object value in vuex actions?

I store data in state as array and I want to change the value of the object. How can I change the id 1 value to true with vuex actions? state.js

const array=[]

mutations.js

storeArray(state, data) {
    state.array = data;
  }

actions.js

async changeValue({ state, dispatch, commit }, id) {
    const item = await state.array[id].value;

    await commit('storeArray', { value: true });

  },

array looks like

[{
    id: "1",
    value: 'false'
}, {
    id: "2",
    value: 'true'
}]

Use Vue.set (https://vuejs.org/v2/guide/reactivity.html)
