Show a different Blade template based on permission. If 'private' then look for a template in the 'private' folder inside the original folder with the same name.

ViewServiceProvider.php

app('view')->creator('*', function (\Illuminate\Contracts\View\View $view) {
    if(env('API_CLIENT_ID') === 'private') {
        $viewValues = explode('/', $view->getPath());


        $alreadyPrivate = ($viewValues[count($viewValues) - 2] === 'private');
        $last = array_pop($viewValues);
        array_push($viewValues, 'private', $last);
        $privateView = implode('/', $viewValues);

        if (file_exists($privateView) && $alreadyPrivate === false) {
            $view->setPath($privateView);
        }
    }
});
