helpful/get_option/{option_name}

This filter can be used to manipulate options before output. Helpful has quite a few options now, which is why you need to pick the option in the code that is important to you.

add_filter('helpful/get_option/{option_name}', function($old_value) {
    $new_value = 'My new value!'
    return $new_value;
});
