Answer 1

I would suggest something like this

let messagesToDelete = [];
telegramBot.sendMessage('some').then((m) => {
  messagesToDelete.push({
    messageId: m.message_id,
    chatId: m.chat.id
  });
}).catch(console.error);

function wipeHistory() {
  messagesToDelete.forEach(m => {
    telegramBot.deleteMessage(m.chatId, m.messageId).then((success) => {
      if (success) {
        messagesToDelete = messagesToDelete.filter((v) => (v.messageId !== m.message_id && v.chatId !== m.chat.id));
      };
    }).catch(console.error);
  });
};

setInterval(wipeHistory, 60 * 10 * 1000);

Answer 2

I will not give out the finished code, but the algorithm will be as follows:
- when adding a message using the `sendMessage` method - remember its `message_id`
- delete messages by the timer using the `deleteMessage` method for each `message_id`
