XF 2.1 Not able to use third party composer library

[sajal]

I want to use this "league/oauth2-client" library.

I have installed it via Composer.

Now when I try to use it in my controller file like this:
use League\OAuth2\Client\Provider\GenericProvider;
use League\OAuth2\Client\Provider\Exception\IdentityProviderException;

I get the error:

Error: Class 'League\OAuth2\Client\Provider\GenericProvider' not found

Any help would be greatly appreciated.
