Why is yii2-migration-utility not connected?

Question

Yii

I want to connect the module www.yiiframework.com/extension/yii2-migration-utility
installed, connected in common/config/main.php

'modules'    => [
            'utility' => [
                'class' => 'c006\utility\migration\Module',
            ],
        ],

after following the link /index.php?r=utility/index an error is generated
Class c006\utility\migration\Module does not exist

So look at the source, maybe there is no such file in the vendors, maybe the namespace is not the same. Documentation often doesn't keep up with changes.
