Why does not see the class in the component?

Question

Yii

Hello!
I install an application to work with Google drive:
https://github.com/la-haute-societe/yii2-flysystem...
I do:

php composer.phar require --prefer-dist la-haute-societe/yii2-flysystem-google-drive "~1.0.0"

Everything seems to be ok! Settled! BUT:
I write in the main.php file in components:

'googleDrive' => [
            'class' => 'lhs\Yii2FlysystemGoogleDrive',
            'clientId'     => '***',
            'clientSecret' => '***',
            'refreshToken' => 'xxx YOU REFRESH TOKEN xxx',
            // 'rootFolderId' => 'xxx ROOT FOLDER ID xxx'
        ],

Next I try $contents = Yii::$app->googleDrive->listContents();
Writes: Class 'lhs\Yii2FlysystemGoogleDrive' not found
Where to dig?

Answer 1

'googleDrive' => [
            'class' => 'lhs\Yii2FlysystemGoogleDrive\GoogleDriveFilesystem',
            'clientId'     => '***',
            'clientSecret' => '***',
            'refreshToken' => 'xxx YOU REFRESH TOKEN xxx',
            // 'rootFolderId' => 'xxx ROOT FOLDER ID xxx'
        ],

I don't want to sound like a bore, but you're importing a library that consists of a couple of dozens of not-so-important code. The library has only one initial commit and is not required.
Make your own component based on this file.
