                ),
            ),

    ),

On Android, you'll have to use RemoteInput and 'apply' action to the notification. Below is the summary and here are the details.

public static final String NOTIFICATION_REPLY = "NotificationReply";

RemoveInput removeInput = new RemoteInput.Builder((Notification_REPLY))
    .setLabel("Approve Comments")
    .build();

Then create a PendingIntent for the reply action as below :

PendingIntent acceptPendingIntent = PendingIntent.getBroadcast(
    context:this,
    REQUEST_CODE_APPROVE,
    new Intent(packageContext:this,NotificationReciver.class)
        .putExtra(KEY_INTENT_APPROVE,REQUEST_CODE_APPROVE),
    PendingIntent.FLAG_UPDATE_CURRENT
);

Then attach the RemoteInput object to an action using addRemoteInput()

NotificationCompat.Action action =
    new NotificationCompat.Action.Builder(ic_delete,
        title:"Approve", acceptPendingIntent)
        .addRemoteInput(remoteInput)
        .build();

Lastly, you'll have to apply the action to notification and display.

NotificationCompat.builder = notificaitonBuilder = new NotificationCompat.Builder(context:this,channelId:"channel_id")
    .addAction(action)
    // set rest of notification attributes e.g. title, auto cancel, icon etc.

You can pass the required information from the 'data' attribute of Firebase notification. You'll have to use onReceive() even to attach reply/buttons at the bottom of the message.
