        .setSmallIcon(R.drawable.img_app_logo)
        .setCustomContentView(remoteViews)
        .setCustomBigContentView(remoteViews)
        .setCustomHeadsUpContentView(remoteViews)
        .setPriority(NotificationCompat.PRIORITY_HIGH)
        .setAutoCancel(true)
        .addAction(optimizeAction)
    cancelAction?.let {
        builder.addAction(it)
    }
    notificationManager.notify(notificationId, builder.build())

You should change the targetSdkVersion from the build.gradle file to something below 31. (30 worked for me)
