Follow specific user to track certain words / hashtags

[c0d3high]

Trying to get tweets containing certain words from a specific user.... any ideas?

require('dotenv').config()
const Twit = require('twit')
const Discord = require('discord.js');
const client = new Discord.Client();


var T = new Twit({
  consumer_key:         process.env.TWITTER_CONSUMER_KEY,
  consumer_secret:      process.env.TWITTER_CONSUMER_SECRET,
  access_token:         process.env.TWITTER_ACCESS_TOKEN,
  access_token_secret:  process.env.TWITTER_ACCESS_TOKEN_SECRET,
  timeout_ms:           60*1000,  // optional HTTP request timeout to apply to all requests.
  strictSSL:            true,     // optional - requires SSL certificates to be valid.
})
client.login(process.env.DISCORD_TOKEN3);
client.once('ready', () => {
  var stream = T.stream('statuses/filter', { follow: [process.env.TWITTER_USER_ID] }) 

  stream.on('tweet', function (tweet) {
    if(tweet.retweeted || tweet.retweeted_status || tweet.in_reply_to_status_id || tweet.in_reply_to_user_id || tweet.delete) {
      // skip retweets and replies ------- new
      return;
  }
    //...
    var url = "https://twitter.com/" + tweet.user.screen_name + "/status/" + tweet.id_str;
    try {
        let channel = client.channels.fetch(process.env.DISCORD_CHANNEL_ID).then(channel => {
          channel.send(url)
        }).catch(err => {
          console.log(err)
        })
    } catch (error) {
            console.error(error);
    }
  })
  })
