use App\Plugins\AppPlugin;
use App\Plugins\PluginEvents;
use App\Plugins\Events\Events\MailTemplatesEvent;

class MyPlugin implements AppPlugin
{
    public static function processEvents(PluginEvents $event): void
    {
        $event->on(MailTemplatesEvent::onMailTemplateDeleted(), function ($template, $deletedBy): void {
            App::getInstance(true)->getLogger()->info('[myplugin] featherpanel:admin:mail_templates:template:deleted ' . json_encode(['template' => $template, 'deleted_by' => $deletedBy]));
