如何重置a-select Ant Design Vue？

<template>
  <a-select v-model="initialValue">
    <a-select-option value="option1">Option 1</a-select-option>
    <a-select-option value="option2">Option 2</a-select-option>
    <a-select-option value="option3">Option 3</a-select-option>
  </a-select>
  <a-button @click="resetSelect">重置</a-button>
</template>

<script>
export default {
  data() {
    return {
      initialValue: '' // 初始值为空
    };
  },
  methods: {
    resetSelect() {
      this.initialValue = ''; // 重置为初始值
    }
  }
};
</script>
