Telegram-bot-sdk: how to send keyboard only without reply

[alainbelez]

currently i send the keyboard using

$keyboard = [
    ['/getcurrentprice'],
    ['/addpricenotify'],
    ['/removepricenotify']
];

$reply_markup = $this->telegram->replyKeyboardMarkup([
    'keyboard' => $keyboard, 
    'resize_keyboard' => true, 
    'one_time_keyboard' => true,
]);

$this->telegram->sendMessage([
    'chat_id' => '-------------', 
    'text' => 'test',
    'reply_markup' => $reply_markup
]);

and the result is

how do you send keyboard only without the "reply" like this (without the red box above)?

I think it is impossible.
