我需要在Google或Apple日历（或支持.ics的任何功能）中创建一个您可以订阅的日历。
预订Google日历中的URL会丢失日历中的大多数事件。这令人困惑，因为它在Apple Calendar中可以完美运行。另外，如果我将浏览器的文字输出另存为.ics文件并导入，那么它在Google和Apple中都可以完美运行。
为什么Google日历仅显示以下事件示例中的“?亡灵节”和“迪士尼+开始流媒体”？

use Spatie\Calendar\Components\Event as iCalEvent;
use Spatie\Calendar\Components\Calendar as iCalendar;
$icalendar = iCalendar::create('AwesomeCalendar');
$icalendar_event = iCalEvent::create()
->name($event->name)
->description($event->description)
->uniqueIdentifier($event->slug)
->createdAt($event->created_at)
->startsAt($event->started_at)
->endsAt(Carbon::parse($event->started_at)->addDays(1))
->fullDay($event->is_all_day);
$icalendar->event($icalendar_event);
return response()
->streamDownload(function () use ($icalendar) {
echo $icalendar->get();
}, 'event.ics');
