'Header/footer doesn't show in page

I tried to override the page--batch.html.twig file, but still, no result.

This is what I get for the user cancelation account process :

Unfortunately, you were so close to finding the answer :)

You can then use twig_tweak to load your regions into the page, with your theme on page--batch.html.twig (header + footer): https://www.drupal.org/docs/contributed-modules/twig-tweak-2x/cheat-sheet

{{ drupal_region('header', 'your_theme') }}
{{ drupal_region('footer', 'your_theme') }}
