Accesing module in admin controller

Yii 2.0 General Discussions

I installed this extension https://github.com/codemix/yii2-localeurls

I made this configuration

'urlManager' => [
           'class' => 'codemix\localeurls\UrlManager',
           'enablePrettyUrl' => true,
           'showScriptName' => false,
           'enableStrictParsing' => false,
           'languages' => [ 'ro', 'en'],
           'enableLanguagePersistence'    => false,
           'languageSessionKey'           => false,
           'languageCookieDuration'       => false,
           'enableLanguageDetection'      => false,
           'enableDefaultLanguageUrlCode' => true,


           'rules' => [
                '<alias:\w+(-\w+)*>'    => 'site/<alias>',
            ],

           'ignoreLanguageUrlPatterns' => [
                '#^admin/(.*)#'          => '#^admin/(.*)#',
           ]

Basically, I have two controllers site and admin, any actionNAME from site controller will match ro/actionName or en/actionName. And any actionName from admin controller will match admin/actionName.

Then I installed and configured this extension https://github.com/PendalF89/yii2-filemanager

And I do not know how to set the filemanager so I can access it ONLY with:

admin/filemanager/file/index

Right now I can access this extension in routes like:

ro/filemanager/file/index
ro/filemanager/file/uploadmanager 
etc.

P.S. sorry for my english;
