Disable notification sound with keeping heads up notification in silent mode.

Thanks for your help.

Problem

My app ringing when silent mode.

code

MainActivity.kt

val channel = NotificationChannel(
    notificationType.channelId,
    notificationType.channelName,
    NotificationManager.IMPORTANCE_HIGH
).apply {
    setSound(uri, attribute)
    enableVibration(true)
    vibrationPattern = createVibrate()
    lightColor = Color.BLUE
}
channel.lockscreenVisibNotification.VISIBILITY_PUBLIC
manager.createNotificationChannel(channel)

PushNotificationListenerService.kt

val notificationBuilder = NotificationComBuilder(this, receivedChannelId)
    .setContentTitle(title)
    .setContentText(text)
    .setSmallIcon(R.drawable.ic_menu_logo)
    .setContentIntent(pendingIntent)
    .setPriority(PRIORITY_MAX)
    .setCategory(CATEGORY_CALL)
    .setSound(defaultSoundUri)
    .setVibrate(createVibrate())
    .setAutoCancel(true)
    .setLights(Color.BLUE, 5000, 10)

things I tried

Switch setSound settings corresponding to silent mode. (This is not working.)
Try to set notificationBuilder.setSilent(true). (Heads up notification deleted.)
Try to change NotificationManager.IMPORTANCE_HIGH to IMPORTANCE_LOW. (Heads up notification deleted.)
