how to parse my inputted chat message from CSGO game?

How do I parse the chat messages I input into the game CSGO? There doesn't seem to be any API calls for it.

var Steam = require('steam');
var fs = require('fs');
var bot = new Steam.SteamClient();



//config
var AccName='';    //account login
var AccPasswd='';  //account passwd
var AuthCode='';   //account auth

var PASSWORD='123';//console password 




var bCaptureMSG=false;
var CaptureID;
var bSendMessage=false;
var MessageReciveID;

var authID;

if (fs.existsSync('sentryfile'))
{
    var sentry = fs.readFileSync('sentryfile');
    console.log('[STEAM] logging in with sentry ');
    bot.logOn({
      accountName: AccName,
      password: AccPasswd,
      shaSentryfile: sentry
    });
}
else
{
    console.log('[STEAM] logging in without sentry');
    bot.logOn({
      accountName: AccName,
      password: AccPasswd,
      authCode: AuthCode
    });
}
bot.on('loggedOn', function() {
    console.log('[STEAM] Logged in.');
    bot.setPersonaState(Steam.EPersonaState.Online);
});


bot.on('message', function(source, message, type, chatter) {
  // respond to both chat room and private messages
  console.log('Received message: ' + message);
  console.log('Received from: ' + source);

  if(bSendMessage){
    if(message==''){
