How can I list Drupal 8 Content Moderation draft
Out of the box, on Drupal, only users with the Bypass content access control permission can see every unpublished post, but that is a permission to give to a very small set of users, such as administrator users.
The other users can only see the unpublished nodes they created.

You can create a module that defines a new permission (e.g. View unpublished content), and implement hook_node_access_records_alter()/hook_node_grants_alter() to grant the view access to those users with the new permission.
