How to correctly write a routing rule in Yii2?

Question

Yii

Hello, I need the user who came to my site to be redirected to the module display.
I'm trying to write the following:

'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'enableStrictParsing' => false,
            'rules' => [
                '/' => 'frontend/web/site-front',
            ],
        ],

Gives 404 error.
Can you please tell me how to correctly configure the routing for my requirement?
Thanks in advance to all who respond.
