stevenmaguire keycloak plugin returns $token variable how to use this token to in yii2 project for single sign on

    index.php() //plugin
`if (!isset($_GET['code']) || !isset($_SESSION['oauth2state'])) {
        // If we don't have an authorization code then get one
        $authUrl = $provider->getAuthorizationUrl();
        $_SESSION['oauth2state'] = $provider->getState();
        header('Location: ' . $authUrl);
        exit;
    
        //Check given state against previously stored one to mitigate CSRF attack
    }
    
    elseif (empty($_GET['state']) || ($_GET['state'] !== $_SESSION['oauth2state'])) {
    
        unset($_SESSION['oauth2state']);
        exit('Invalid state, make sure HTTP sessions are enabled.');
    } 
    
    else {
    
        // Try to get an access token (using the authorization coe grant)
        try {
            $token = $provider->getAccessToken('authorization_code', [
                'code' => $_GET['code']
                    
                    
            ]);
    //        $token = $provider->getAccessToken('refresh_token', ['refresh_token' => $token->getRefreshToken()]);
    //                 echo $token->getRefreshToken();       
    
    //        print_r($token);
    
        } catch (Exception $e) {
    //        echo 'tttttttttttttttttt';
            exit('Failed to get access token: ' . $e->getMessage());
        }
    
        // Optional: Now you have a token you can look up a users profile data
        try {
    
            // We got an access token, let's now get the user's details
            $user = $provider->getResourceOwner($token);
    //        print_r($user);
            // Use these details to create a new profile
    //        printf('Hello %s!', $user->getName());
        } catch (Exception $e) {
            exit('Failed to get resource owner: ' . $e->getMessage());
        }
    
        // Use this to interact with an API on the users behalf
    //   echo $token->getToken();
        
    }`
