RecordApp.UniPageOnShow is not a function

[IlangshenI]

import Recorder from 'recorder-core'
import '../../../../../uni_modules/Recorder-UniCore/app-uni-support.js'
// #ifdef MP-WEIXIN
import 'recorder-core/src/app-support/app-miniProgram-wx-support.js'
// #endif

import RecordApp from 'recorder-core/src/app-support/app.js'
// import { ref, getCurrentInstance, onMounted, onUnmounted } from 'vue';
import { onShow } from '@dcloudio/uni-app'
const isVue3=ref(true);
const recpowerx=ref(0);
const recpowert=ref("");
const reclogs=ref([]);
const isRunning = ref(false); // 控制计时器状态v
const currentTime = ref(0); // 存储当前时间（秒）
var vue3This=getCurrentInstance().proxy; //必须定义到最外面，getCurrentInstance得到的就是当前实例this
onMounted(()=>{
vue3This.isMounted=true;
RecordApp.UniPageOnShow(vue3This); //onShow可能比mounted先执行，页面准备好了时再执行一次
});
onUnmounted(()=>{
RecordApp.Stop(); //清理资源，如果打开了录音没有关闭，这里将会进行关闭
});
onShow(()=>{
if(vue3This.isMounted) RecordApp.UniPageOnShow(vue3This); //onShow可能比mounted先执行，页面可能还未准备好
});

最后报错RecordApp.UniPageOnShow is not a function
大佬们怎么解决呢

import RecordApp from 'recorder-core/src/app-support/app.js'
这句要放到 app-uni-support.js 前面
