Adding ARC Values to response from openid-connect-generic to IdP

How would you add an arc value to the response that openid-connect-generic send to IdP?

This time I will answer my own question. you can use the openid-connect-generic-auth-url filter. Works like a charm.

// Add Arc Values
add_filter('openid-connect-generic-auth-url', function( $url ) {
    $url.= '&acr_values=allow_reg%3Atrue';
    return $url;
});
