Hi guys! At the moment I'm working on a chat-bot Steam, the essence of which will be giving out things for winning in the game, and all this will happen right in the bot, but I ran into the problem that I can not get data from the user: 
  client.on('friendOrChatMessage', (senderID, message) => {
if (message.indexOf("/bet %user number%") == 0){
			client.chatMessage(senderID, 'Your bet is: ' + %user number%);
		}
});
where %user number% is the number that the user enters, but I do not know how it can be implemented :C   Is it even possible to do this and how? Please help me!
