Vue 3 is it possible to mount on an event?

Question

Vue.js

In the process of developing the site, the task arose to show the generated page element on Vue 3 by event, that is, until some kind of event occurs, vue should not replace what is inside the vue-tag-name tag (the same #app)
since initially there is another necessary content generated by the server side of the site
here is an example of how everything is roughly arranged manual assembly of vue 3 + webpack in the resulting file there should be no vue directives, this is not a SPA or MPA, just some elements of the site are implemented on vue.

import { createApp } from 'vue';
import App from '../components/App.vue';

createApp(App).mount('vue-tag-name') // работает но заменяет сразу

var app = createApp(App);
 $(window).on('scroll', function(){
            app.mount('vue-tag-name');
    }); // не работает заменяет на пустоту но без ошибок

Answer 1

The code is working, most likely, the event is simply not called. Probably the output agent should be hung up on other element.
