How to change mediawiki's FlaggedRevs permissions?

Question

MediaWiki

Hello everyone, friends.
There is a task:
1. Open Wikipedia, everyone can make changes. Create pages/delete pages/edit pages.
2. Changes made must be sent for moderation.
3. Only the administration can apply changes that are being moderated.
There is a user who is a member of groups: Administrators, Autoverified Members, Bureaucrats, Members
There are settings in localsettings:
# FlaggedRevs
$wgGroupPermissions['*']['reviewer'] = false;
$wgGroupPermissions['sysop']['reviewer'] = true;
When changing pages, they go to moderation. The current user cannot check (I don't see an explicit button).
How to be?
