How to prevent android quick reply notification from being stuck in loading?

My app uses the Android N's new quick-reply feature to quickly take notes from a fixed notification, without having the user to open an activity.

However, I would like the notification to be reset to its initial state after the user sends the quick reply message, without having to dismiss the notification.

Here is my code:

NotificationCompat.Builder builder = new NotificationCompat.Builder(this, Build.VERSION.SDK_INT >= Build.VERSION_CODES.O ? createChannel() : "").setSmallIcon(android.R.mipmap.sym_def_app_icon).setContentTitle("My Awesome App").setContentText("Doing some work...").setContentIntent(pendingIntent);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            android.support.v4.app.RemoteInput remoteInput = new RemoteInput.Builder(BookmarkCreatorReceiver.TXT_REPLY).setLabel("Reply").build();

            Intent replyIntent = new Intent(this, BookmarkCreatorReceiver.class);
            PendingIntent replyPendingIntent = PendingIntent.getBroadcast(this, 0, replyIntent, 0);

            NotificationCompat.Action action = new NotificationCompat.Action.Builder(android.R.drawable.ic_dialog_email, "Bookmark", replyPendingIntent).addRemoteInput(remoteInput).build();
            NotificationCompat.Action actionQuick = new NotificationCompat.Action.Builder(android.R.drawable.ic_dialog_email, "Quick", replyPendingIntent).build();
            builder.addAction(action);
            builder.addAction(actionQuick);
        }

        startForeground(NOTIFICATION_ID, builder.build());

The problem is that once the user sends a message and the Broadcast receiver is called, the notification stays in the loading state like this:

How can I remove the loading message, without having to discard the notification?

Per the Notifications in Android N blog post:

After you’ve processed the text, you must update the notification by calling notify() with the same id and tag (if used). This is the trigger which hides the Direct Reply UI and should be used as a technique to confirm to the user that their reply was received and processed correctly.

Also note:

For most templates, this should involve using the new setRemoteInputHistory() method which appends the reply to the bottom of the notification.

This ensures that users see the text they entered was properly handled.
