vue3.2如何将写hooks呢？

<template>
    <div>
        <el-button @click="addHanlder">新增</el-button>
        <ul>
            <li v-for="item in listArr" :key="item.id"> {{ item.name }} </li>
        </ul>
    </div>
</template>
<script lang="ts" setup>
import {  ref} from 'vue'
// 导入新增模块的业务逻辑，注意不能够写成add.ts
import addHooks from './add'
// 定义接口
interface listType{
    name?:string,
    age ?:number,
    id:string,
    // 可以有任意多个字段-任意类型
    [propN:string]:any,
}
let listArr=ref<listType[]>([
    {name:'张三',age:21,id:'001'},
    {name:'李四',age:20,id:'002'},
    {name:'周六',age:28,id:'004',aa:'xx'},
])
// 使用新增模块
let { addHanlder }=addHooks(listArr.value);
</script>

// 新增功能的逻辑
// 注意这里需要说明listArr的参数类型哈 { name?: string; age?: number; id: string }[]
function addHooks(listArr: { name?: string; age?: number; id: string }[]) { 
    function addHanlder() { 
        listArr.push(
            {name:'王五',age:24,id:'005'}
        )
    }
    return {
        addHanlder
    }
}
export default  addHooks
