Backspace typewriter effect

Question

I did a typewriter effect. However, I would like to do a backspace effect where it would individually remove letters. I've tried so many things but I couldn't get it right. This is my current code:

     IEnumerator PlayBookName()
     {
         bookNameString = "Witch of the South";
         foreach (char c in bookNameString)
         {
             bookName.text += c;
 
             yield return new WaitForSeconds(0.02f);
 
         }
     }

Code NOT tested

  IEnumerator EraseBookName()
  {
      WaitForSeconds wait = new WaitForSeconds(0.02f);
      while(bookName.text.Length > 0)
      {
          bookName.text = bookName.text.Substring(0, bookName.text.Length - 1);
 
          yield return wait;
      }
  }

However, I would suggest using TextMeshPro's maxVisibleCharacters instead (both for typing and erasing effects)
