我在列表页的快速搜索前新增了一个上传按钮，并设置了捕获事件。但是无效

框架

<template #quickSearchPrepend>
  <el-upload ref="upload" class="upload-demo" action="#" :limit="1" accept=".csv" :auto-upload="false" :before-upload="ChooseCsv" :show-file-list="false">
                    <template #trigger>
                        <el-button type="success">
                            <Icon color="#ffffff" name="el-icon-Upload" />
                            <span class="table-header-operate-text">导入</span>
                        </el-button>
                    </template>
                </el-upload>
            </template>



const ChooseCsv = ({ file }) =>{
    console.log(file);
}

结果无打印信息，界面以及按钮正常渲染
