How to properly configure url for authclient in Yii2?

Question

Yii

Hello!
The essence of the problem is this... I
installed this extension https://github.com/yiisoft/yii2-authclient
I added my authorization client and configured it according to the instructions.
I got this config

'components' => [
        'authClientCollection' => [
            'class' => \yii\authclient\Collection::class,
            'httpClient' => [
                'responseConfig' => [
                    'format' => 'json',
                ]
            ],
            'clients' => [
                'my-client' => [
                    'class' => \yii\authclient\OpenIdConnect,  
                    .........

Now, in order for my-client to work, I pass authclient=my-client to $_GET and the request goes where it needs to, but it comes back without this parameter and I get 404.

Can anyone come across how to set this thing up to work?
