Text and FontAwesome alignment in a Bootstrap 5 button

Question

I am trying to figure out how to do something with a Bootstrap 5 button. I would like to be able to have the text label of the button left-justified and the FontAwesome icon right-justified. If I use a fixed-width button, how do I make sure it scales according to screen size along with all of the other content? Here's my button now, but the icon is on the wrong side, and nothing is justified:

            <button type="button" class="btn btn-labeled btn-success">
                <span class="btn-label"><i class="fa fa-angle-right"></i></span>

            </button>

Thank you in advance for your help, everyone!
