Flowbite modal not showing

I am trying to use flowbite components in my project but they are not working , (e.g dropdown, modal,...).

I followed the documentation but nothing works.

I'm using vuejs 3, Vite v2.9.9.

This is my main.js file:

import { createApp } from 'vue'
import App from "@/App.vue";
import router from './router/index'
import store from './state/store'

// Imported css file [TailwindCSS]
import './index.css'

// Imported flowbite
import 'flowbite';

createApp(App)
    .use(router)
    .use(store)
    .mount('#app')

modal.vue

<template>

  <!-- Modal toggle -->
  <button class="block text-white bg-blue-700 hover:bg-blue-800 focus:ring-4 focus:ring-blue-300 font-medium rounded-lg text-sm px-5 py-2.5 text-center dark:bg-blue-600 dark:hover:bg-blue-700 dark:focus:ring-blue-800" type="button" data-modal-toggle="default-modal">
    Toggle modal
  </button>

  <!-- Main modal -->
  <div id="default-modal" aria-hidden="true" class="hidden overflow-y-auto overflow-x-hidden fixed right-0 left-0 top-4 z-50 justify-center items-center h-modal md:h-full md:inset-0">

I had the same problem at svelte.

I finally solved it:

import 'flowbite/dist/flowbite.js'
...
let modal = new Modal(document.getElementById('modalId'),{placement:'center'})
...
<button on:cllick={()=>modal.show()} >Open</button>
