Moderate my blog author’s topics before gets published?

go to users page in your dashboard.

/wp-admin/users.php

select the users you want to moderate.

above the users list you have a drop down called “change role to”

select the new role as “contributor” and click “change”.

Now these users posts will be held for review and you can approve them for publishing.

but here (https://codex.www.ads-software.com/Roles_and_Capabilities) says that the contributor can edit_posts, delete_posts and read. Nothing else..
