如何在antd中更改upload组件中的上传文本？

import { Upload } from 'antd';

render() {
  return (
    <Upload
      name="file"
      action="/upload"
      beforeUpload={this.beforeUpload}
      onChange={this.handleChange}
      customRequest={this.customRequest}
      showUploadList={false}
    >
      <Button>
        上传文件
      </Button>
    </Upload>
  );
}

render() {
  const uploadProps = {
    name: 'file',
    action: '/upload',
    beforeUpload: this.beforeUpload,
    onChange: this.handleChange,
    customRequest: this.customRequest,
    showUploadList: false,
    // 修改上传文本
    children: (
      <Button>
        自定义上传文本
      </Button>
    ),
  };

  return (
    <Upload {...uploadProps}>
      {uploadProps.children}
    </Upload>
  );
}
