vue3中怎么使用element-plus调用message

  mounted(){
    (this as any).$message.success("this.$message");
  }

//helloworld.Vue
import { getCurrentInstance, defineComponent,onMounted } from 'vue';
export default  = defineComponent{
setup(omprops,content){
    onMounted(()=>{
      getCurrentInstance()?.appContext.config.globalProperties.$message.success("聪明");
    })
}

//main.ts
import { createApp } from 'vue'
import App from './App.vue'
import element from 'element-plus'
import 'element-plus/lib/theme-chalk/index.CSS'
import {ElMessage} from 'element-plus'
const app = createApp(App)
app.use(element)
//如果没有全局引用element，还需写下面一句
//app.config.globalProperties.$message = ElMessage;
app.provide('$message', ElMessage)
app.mount('#app')

//helloworld.vue
import { inject, defineComponent,onMounted } from 'vue';
export default  = defineComponent{
setup(omprops,content){
    onMounted(()=>{
      (inject('$message') as any).success("inject");
    })
}

//helloworld.vue
import { inject, defineComponent,onMounted } from 'vue';
import { ElMessage } from 'element-plus'
export default  = defineComponent{
setup(omprops,content){
    onMounted(()=>{
      ElMessage.success('按需引入');
    })
}

this.$message({
  message: "提示信息",
  type: "success"
})

ElementUI.Message({
  message: '提示信息',
  type: 'warning'
});
