Every user with the "patrol" permission is able to review article changes. Only the "sysop" (admin) does have this permission by default. So you need to add some sysops or you can add "patrol" to your desired group:
$wgGroupPermissions['team']['patrol'] = true;
The next interesting point is the auto-review. This means changes done by the "sysop" and "bot" are automatically reviewed as both have this permission:
$wgGroupPermissions['bot']['autopatrol'] = true;
$wgGroupPermissions['sysop']['autopatrol'] = true;
Feel free to add this permission to your group as well:
$wgGroupPermissions['team']['autopatrol'] = true;
I hope this information was helpful. I think it should be part of the extension article, but I don't really understand how to insert a new text without getting problems with the translation ids.

Thank you. I've added a tweaked version of that to Manual:Patrolling, and linked to that here. Regarding the translation IDs, you don't need to worry about them when adding text. When modifying existing text, see Help:Extension:Translate/Page_translation_example#Step_4:_Making_changes.
