Display fixed number of words in textbox at a time Unity C#

Question

Hi I have been trying to figure this out with no luck. I am receiving text from an API and sometimes the text is received with over 10 words and sometimes only one word. I would like to write a script that will only allow up to 3 words to be displayed at a time in a text box on screen.

Then after 2 seconds it will move to the next three words. If there is less than three words it will only display the remaining words. once it is finished I would like to call the API again to get more text. Can anyone help with this please?

I have been trying to create a lot of if statements but I am not sure how I would get the logic right? I think I might be overcomplicating this. Please help if there is an easier way. I have included some code that I have started with. Thank you!

Here's how I would do

I am receiving text from an API
only allow up to 3 words to be displayed at a time
after 2 seconds it will move to the next three words
once it is finished I would like to call the API again to get more text

Get text from api
Display it 3 words at the time, for 2 seconds of each 3-word-group
Repeat it forever

IEnumerator Start() {
  while (true) {
    var textFromApi = GetSomeTextFromSomewhere();
    yield return StartCoroutine(DisplayText(textFromApi));
  }

}


IEnumerator DisplayText(string text) {
  var start = 0;
  var take = 3;

  var arrayOfWords = text.split(' ').ToList();

  for (int i = 0; i < arrayOfWords.Count; i += take) {
    var displayList = arrayOfWords.Skip(i).Take(take);
    var displayText = String.Join(' ', displayList);
    
    textDisplay.text = displayText;

    yield return new WaitForSeconds(2);
  }
}
