Laravel中的松弛通知-to（）函数什么都不做？

Question

我正在尝试使用laravel 6使用此处的文档向各个用户发送通知：https://laravel.com/docs/6.x/notifications#slack-notifications

我的from和to函数似乎什么都没做。

// call notification
Notification::route('slack', $slackUrl)->notify(new notifyHours($event->user));

App \ Notifications \ notifyHours

// send DM
public function toSlack($notifiable)
 {
     return (new SlackMessage())
         ->from('Puffin', ':puffin:') // doesn't seem to do anything
         ->to('@U4KFXXXXX')           // doesn't seem to do anything
         ->image('https://XXX.png')
         ->content("Hi! Make sure I am up to date!")
         ->attachment(function(SlackAttachment $attachment) use ($notifiable) {
            $attachment->title('Your Hours', 'https://xxx/tasks')
                           ->fields([
                                'Today' => $this->hours->today.' hours',
                                'This Week' => 'You worked '.$this->hours->week. ' hours.'
                            ]);
         });
 }

通知如何发送到整个通道，而不是我在to（）函数中定义的用户？

根据代码，to()方法仅接受一个频道，而不是该团队的用户。

   /**
     * Set the Slack channel the message should be sent to.
     *
     * @param  string  $channel
     * @return $this
     */
    public function to($channel)
    {
        $this->channel = $channel;

        return $this;
    }
