How to send message outside webhooks?

[nightrider77]

require_once("./vendor/autoload.php");
$bot_api_key  = ':';
$bot_username = '';
try {
   $bot = new Longman\TelegramBot\Telegram($bot_api_key, $bot_username);
   ..... ? // $bot->sendMessage($user['telegram_chatId'], $messageText);
}

If I just execute sendMessage on $bot, I will get error

Fatal error: Uncaught Error: Call to undefined method Longman\TelegramBot\Telegram::sendMessage()

Why there is no information on how to deal with this without any webhooks, e.g. if you just need to notify website users with some information.

Thanks.

I will reply to myself. But it's very strange there is no simple method to send a simple message...
The lack of information in the readme.md is also very strange.

use Longman\TelegramBot\Request; 
require_once("./vendor/autoload.php");
$bot_api_key  = ':';
$bot_username = '';
try {
   $bot = new Longman\TelegramBot\Telegram($bot_api_key, $bot_username);
   $result = Request::sendMessage([
        'chat_id' => $user['telegram_chatId'],
        'text'    => $messageText,
   ]);
} catch (Longman\TelegramBot\Exception\TelegramException $e) {
  // log telegram errors
  // echo $e->getMessage();
}
