How to alias a state name?

[doglex]

// worker.js 
import {defineStore} from "pinia";
import {ref} from "vue";

export const useWorker = defineStore('worker.js', () => {
    const x = ref({})
    function setMethodNew() {
        x.value = {}
    }
    return {x, setMethodNew}
})

// demo.vue 
import {useWorker} from 'worker.js'
const worker = useWorker ()
x = ref(worker.x)   // alias here
x = {"a": 1}
worker.setMethodNew() 
console.log("after value", x.value)

x.value should be '{}' , but got '{"a": 1}' ， why alias not working?
