Bootstrap 5 Floating Action Button

I have the following code to represent a floating action button:

.dropup .hide-toggle.dropdown-toggle::after {
    display: none !important;
}

<div class="dropup position-absolute bottom-0 end-0 rounded-circle m-5">
    <button type="button" class="btn btn-success btn-lg dropdown-toggle hide-toggle" data-bs-toggle="dropdown" aria-expanded="false" aria-haspopup="true">
        <i class="fa-solid fa-plus"></i>
        <span class="visually-hidden">Add Category</span>
    </button>
    <ul class="dropdown-menu">
        <li>
            <a class="dropdown-item" href="#">...</a>
        </li>
    </ul>
</div>

But I'm having an issue hiding the toggle icon in the .dropdown-toggle despite having a CSS rule to have it not display.

What can I do to remove the icon?

Solution

Are you sure it's not working? I see no icon here.

.dropup .hide-toggle.dropdown-toggle::after {
  display: none !important;
}
