I am currently learning Vue.js and have some experience with Bootstrap. When I saw you can use Bootstrap with Vue.js, I thought I would try it out. My code is rather simple, a dropdown and a popover. The dropdown works but the popover doesn’t. I am using Bootstrap 5 and Vue.js 3. I installed popper-js/core as well. Does my main.js file need more imports? BTW, I used vue/cli to create my project.

app.vue

<template>
  <img alt="Vue logo" src="./assets/logo.png">
  <HelloWorld msg="Welcome to Your Vue.js App"/>
  <h1>Bootstrap</h1>
    <div class="container">
      <div class="btn-group">
        <button type="button" class="btn btn-danger dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
          Action
        </button>
        <ul class="dropdown-menu">
          <li><a class="dropdown-item" href="#">Action</a></li>
          <li><a class="dropdown-item" href="#">Another action</a></li>
          <li><a class="dropdown-item" href="#">Something else here</a></li>
          <li><hr class="dropdown-divider"></li>
          <li><a class="dropdown-item" href="#">Separated link</a></li>
        </ul>
      </div>  
      <button type="button" class="btn btn-secondary" data-bs-container="body" data-bs-toggle="popover" data-bs-placement="top" data-bs-content="Top popover">Popover on top</button>
      <button type="button" class="btn btn-secondary" data-bs-container="body" data-bs-toggle="popover" data-bs-placement="right" data-bs-content="Right popover">Popover on right</button>
      <div class="text-center my-3">
