How can I add Custom Plugin to tinymce.v4

I am using tinymce version4 with vue js , after i follow tinymce official documentations and implementd in my project i get error field to load "../plugins/example/plugin.js"

so here is my code

<template>
    <div class="container">
        <h2 class="">Tinymce-Vue</h2>
        <editor id="app-editor" 
                api-key="jh5j9j89wyv5mbctvucc67e0o5ba3q7v4xkldjfoaqv74glt" 
                :init="inital" 
                v-model="content">
        </editor>
    </div>
</template>

<script>
import editor from '@tinymce/tinymce-vue';
import tinymceConfig from './config/tinymce';

export default {
    data(){
        return {
            content: '',
        }
    },
    components: {
        editor
    },
    computed: {
        inital(){
            return tinymceConfig.config;
        }
    }
}
</script>

and config.js file look like so …

const config = {
    select: "#app-editor",
    plugins:"wordcount  example",
    toolbar1: "wordcount |  example",
    external_plugins: {
        example: "../plugins/example/plugin.js",
    },
}

export default {config};

and plugin.js file also look like so :

tinymce.create('tinymce.plugins.
   init: function(editor, url) {
            editor.addButton( 'example', {
    text: 'example',
    icon: false,
    type: 'menubutton',
    menu: [
          {
           text: 'Menu 1',
           onclick:function() {
                 alert("I am Menu 1);
               }
           },
          {
           text: 'Menu 2',
           onclick:  function() {
                  alert("I am Menu 2);
               }
          }
          ]
 });
   },
      
   createControl: function() {
          return null
   },
      
tinymce.PluginManager.add('example', tinymce.plugins.example)

so how to fix it…

Thank you very much @lnewson to help me understand this issue as I expected.

@OmdaMukhtar the docs for external plugins is here: https://www.tiny.cloud/docs-4x/configure/integration-and-setup/#external_plugins The purpose of it is when you want to load a plugin that’s outside the normal plugins directory or when it isn’t bundled as part of your application. Custom plugins generally fall into this category, which is why you’ve probably seen it suggested before.
