bootstrap 5 multiple nested offcanvas

I want to have a multiple nested offcanvas for Bootstrap 5. When I click a button, the first offcanvas should be opened and then click another button which is on the first offcanvas, the second offcanvas should be opened over the first offcanvas and the first offcanvas should not be closed. I will make second one smaller and so the first one still be shown.

<a class="btn btn-primary" data-bs-toggle="offcanvas" href="#offcanvasExample" role="button" aria-controls="offcanvasExample">
            <i class="fas fa-bars"></i>
        </a>
        <a class="btn btn-primary" data-bs-toggle="offcanvas" href="#offcanvasExample2" role="button" aria-controls="offcanvasExample">
            <i class="fas fa-bars"></i>
        </a>
        <a class="btn btn-primary" data-bs-toggle="offcanvas" href="#offcanvasExample3" role="button" aria-controls="offcanvasExample">
            <i class="fas fa-bars"></i>
        </a>
        <a class="btn btn-primary" data-bs-toggle="offcanvas" href="#offcanvasExample4" role="button" aria-controls="offcanvasExample">
            <i class="fas fa-bars"></i>
        </a>

        <div class="offcanvas offcanvas-start" tabindex="-1" id="offcanvasExample" aria-labelledby="offcanvasExampleLabel">
            <div class="offcanvas-header">
                <h5 class="offcanvas-title" id="offcanvasExampleLabel">Offcanvas</h5>
                <button type="button" class="btn-close text-reset" data-bs-dismiss="offcanvas" aria-label="Close"></button>
            </div>
            <div class="offcanvas-body">
                <div>
                    Some text as placeholder. In real life you can have the elements you have chosen. Like, text, images, lists, etc.
                </div>
                <div class="dropdown mt-3">
                    <a class="btn btn-primary" data-bs-toggle="offcanvas" href="#offcanvasExample6" role="button" aria-controls="offcanvasExample">
