I Need Rounded Corners On Bootstrap List Group

Hello everyone, I have a laravel app and I am using list-group in one of my views that has square corners. I want it to have rounded corners instead. Bootstrap version is 4. I need it doing quickly with minimal fuss. Shouldn't be hard for someone who knows how. If this is carried out correcly and quickly more jobs will follow. Experience with laravel, bootstrap, html and css.
