  - The save_contentdata method allows the administrator to save the GDPR cookie notice to the database as a page post type.
  An authenticated user such as a subscriber can use it to put any existing page or post (or the entire website) offline by changing their status.
  Additionally, it is possible to delete or change their content. Injected content can include formatted text,
  local or remote images as well as hyperlinks and shortcodes.

  - The autosave_contant_data method is used to save the GDPR cookie info page while the admin is editing it.
  An authenticated user can use it to inject JavaScript code, which will be loaded and executed each time someone,
  authenticated or not, visits the '/cli-policy-preview/' page.");
