vue3 createVNode 插槽使用第三方组件必须单独引入？已全局引入有没有办法不引入？

Question

封装dialog

import { createVNode, render} from 'vue';
import {ElDialog} from 'element-plus'
const open = (title:string, component?:any, options?: object) => {
    const container = document.createElement('div')
    console.log(component);
    
    const comp = createVNode(
        ElDialog,
        {
            modelValue: true,
        },
        {
            default: () => component(),
            // footer: () => createVNode(ElButton, {}, '321'),
            header: () => title
        }
    )
    render(comp, container)
    document.body.append(container.firstElementChild!)
}

export default{
    open
}

如果引入 ElButton 调用 正常 button 能够正常展示出来

import { defineComponent } from "vue";
import {message, dialog} from '../utils'
import { ElButton } from "element-plus";
export default defineComponent({
    setup(){
        const showMessage = () => {
            message.error('123')
            
        }
        const showDialog = () => {
            dialog.open('123', () => <ElButton type="primary">321</ElButton>)
        }
        return () => <>
            <el-button onClick={showMessage}>message</el-button>
            <el-button onClick={showDialog}>dialog</el-button>
        </>
    }
})

如果不引入 ElButton 使用全局注册的 el-button 则不能够正常展示

import { defineComponent } from "vue";
import {message, dialog} from '../utils'
export default defineComponent({
    setup(){
        const showMessage = () => {
            message.error('123')
            
        }
        const showDialog = () => {
            dialog.open('123', () => <el-button>321</el-button>)
        }
        return () => <>
            <el-button onClick={showMessage}>message</el-button>
            <el-button onClick={showDialog}>dialog</el-button>
        </>
    }
})

好像必须得引入，可以用resolveComponent动态引入
