Arranging Campaigns for display by the Wordpress Widget

I have a client who's site runs on Wordpress Divi builder. We have the widget working to display the archive of their emails but they are requesting the archive list be displayed in chronological order. I've looked at basic (list) HTML code but that won't work. Is there a way to set the widget code to recognize the date the emails were created to affect the listing in the site? Thanks in advance,
