Twitter API v2 and Tweepy, how to get tweet author for streamed tweets?

I am trying to filter out tweets that include a specific hashtag, which works great, I can even display the text. But additionally, I want to print the user_screenname or author name. But it seems like my class can only display the text of the tweet and every other value is None or 0.

class MyStream(tweepy.StreamingClient):


# This function gets called when the stream is working
def on_connect(self):

    print("Connected")


# This function gets called when a tweet passes the stream
def on_tweet(self, tweet):

    # Displaying tweet in console
    if tweet.referenced_tweets == None:
        
        #-------------Doesnt Work----------------------------    
        #print(tweet.created_at)

        print(tweet.text)
        
        #-----------Doesnt Work---------------------------
        #print(tweet.author_id)
        #client.like(tweet.id)
      
        #Doesnt work
        #client.get_user(username=tweet.user_screenname)

      
        #---------Store in CSV------------
        #data.append([tweet.created_at, tweet.user.screen_name, tweet.text])
        #df = pd.DataFrame(data, columns=columns)
       # df.to_csv('StreamTweets.csv')

        # Delay between tweets
        time.sleep(0.1)

How can I display the name of the author of the tweet? tweet.created_at, author_id, tweet.id all return none but tweet.text works fine. Using Twitter API v2 and Tweepy.

Thanks guys!
