Adding Search/Submit Button

Hello. I am working up a new client website (https://mattson-spares.com/), and I have created a page that is dedicated to searching (https://mattson-spares.com/search/). When I insert the shortcode ([ivory-search id=”884″ title=”Search Form”]), the search box appears just fine. The function of the search box also works, but only if the user presses enter/return on their keyboard while they are focused on the box. There is no submit button.

I would like to add a submit button for those who are more mouse-oriented and will be more comfortable pressing the submit button with their mouse as opposed to simply typing and pressing enter/return after they type their search. I can’t seem to locate that in the settings or in any help documentation.

Any help and insight is appreciated. Thank you.
