How do I play an animation once on button click?

I am trying to make an animation play every time a button is pressed, but I can’t figure out how to make it work. It either plays multiple times or it just plays once and doesn’t work the next time I press the button. How can I fix this using C#?

Here's my code. When I press the button the animation just plays on an endless loop.

 [SerializeField] private Animator animationController;
 
     public void CorrectAnswer () {
         if (currentLevel + 1 != Levels.Length) {
             Levels[currentLevel].SetActive(false);
             currentLevel++;
             Levels[currentLevel].SetActive(true);
         }
         score += 1;
         scoreText.text = score.ToString();
         if (score <= 0) {score = 0;}
 
         animationController.SetBool("playAnimation", true);
     }

Here's my animator. I have it so that it the play animation bool is true, it goes from its default state to the animation, but if it is false it goes back to its default state.
