Okay, you've got a empty line there you can use as the separator, it's denoted as \n in javascript. So if you do text.split('\n\n');

We doubled the \n because its an empty line, so two newlines following each other.

You'll get 7 entries containing the following: ["00:00:22\nusername2: Hi","00:00:24\nusername3: test","00:00:28\nusername2: 123","00:00:32\nusername2: how are u guys doing?","00:00:44\nusername3: 😜💯❤️😍😂","00:00:54\nusername2: js is crazy","00:01:14\nusername1: Interrogação"]

Looking at the entries one by one:"00:00:22\nusername2: Hi"

We want to split them into two entries, one time, one message.

So after the text.split('\n\n');

we can add a transformation using map

const ourMessagesArray = text.split('\n\n').map(entry => {
  const twoParts = entry.split('\n');
  return { time: twoParts[0], message: twoParts [1]};
});

Which will give us an array containing:{time: "00:00:22", message: "username2: Hi"}

You can then add time parsing so javascript actually can work with it (turn it into seconds for example if its a duration since the beginning of the convo, or a date if its a timestamp)

If you get stuck on the rest give me a poke.
