l5scaffold and pagination with bootstrap 4.0

As you probably know pagination is not working in l5scaffold (https://github.com/alnutile/l5scaffold).

Original author use Bootstrap 3.x. I wish to use 4.x.

Can you share with community how to fix it?

In source code command is:

{!! $classname->render() !!}

At user browser above code is translated to:

                <ul class="pagination">
                    <li class="disabled"><span>&laquo;</span></li>
                    <li class="active"><span>1</span></li>
                    <li><a href="http://xxxxxx.dev/schedules?page=2">2</a></li>
                    <li><a href="http://xxxxxx.dev/schedules?page=2" rel="next">&raquo;</a></li>
            </ul>

``

Which is NOT displayed properly in BS4!
