Is there a way to style the icon of a completed step in Angular Materials stepper module? When I complete a step it adjusts the icon to a check mark. I'm trying to adjust the background color of the icon as well. My code is similar to the example here with linear mode enabled: https://material.angular.io/components/stepper/overview
When I look in the DOM the only attribute that changes when it is completed is the 'ng-reflect-ng-switch' attribute. I'm not sure how I can target this element in order to style it upon completion. Hopefully someone can point me in the right direction. Thanks!
