Which parameter is responsible for the list of authors in Wordpress?

Question

WordPress

When editing pages, there is a property, like "Authors", in which you can select the author of that page. From this, for user roles, you can restrict access to your / someone else's pages.
But this list only shows site administrators. What parameter can be responsible for the access of the user role in finding the list of authors?

Answer 1

Each user or user group has certain rights.
For example, the following user groups can publish articles (posts): Authors, Editors, Administrators, Super Administrators (WPMU). In the admin panel, you see exactly the users from these groups.
You can install the users role editor plugin to add rights to a user or group of users.
