Val NOTIFICATION_ID = 101

Question

Val NOTIFICATION_ID = 101

val CHANNEL_ID = "Chanelll"

val builder = NotificationCompat.Builder(this, CHANNEL_ID)
.setSmallIcon(R.drawable.ic_launcher_foreground)
.setContentTitle("Напоминание")
.setContentText("111111111")
.setAutoCancel(true)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)

with(NotificationManagerCompat.from(this)) {
notify(NOTIFICATION_ID, builder.build())
}

Почему этот код не выводит уведомления?
