How can I style the webform submissions table? Using Drupal 9 and Webform, I'm unable to find the twig template used to output /contact/form/submissions.  Is there a place in the documentation that lists the twig templates?  I see there is a View created that looks like it has submissions, but disabling it doesn't break the page.  If there is a better way to style it, that could also work.

If you override the WebformSubmissionListBuilder, you can do almost anything you want to the results, including custom theming.
