Bootstrap 4.5.0:我的切换按钮出现在我的品牌形象/名称的右边?我如何将它放在左边？

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <button class="navbar-toggler order-first" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <a class="navbar-brand" href="#">品牌形象/名称</a>
  <div class="collapse navbar-collapse" id="navbarNav">
    <ul class="navbar-nav">
      <li class="nav-item active">
        <a class="nav-link" href="#">链接1</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">链接2</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">链接3</a>
      </li>
    </ul>
  </div>
</nav>
