how to stop Javascript countdown at 0 [duplicate]

I’m trying to create a countdown for a pomodoro app but I don’t know how to stop it when it reaches 0. I’ve tried: clearInterval, minutes.innerHTML = “0”, and adding return with the condition if(minutes <= 0 && seconds <= 0)

       <div class="card work">
        <h2>Work</h2>
        <p id="stopwatch">1:00</p>
        <button id="start">Start</button>
      </div>

    const start = document.querySelector("#start");
    start.addEventListener("click", updateCountdown);

    const startingMinutes = 1;
    let time = startingMinutes * 60;

    const countdownEl = document.querySelector("#stopwatch");

    setInterval(updateCountdown, 1000);

      function updateCountdown() {
      const minutes = Math.floor(time / 60);
      let seconds = time % 60;
      seconds = seconds < 10 ? "0" + seconds : seconds;
      countdownEl.innerHTML = `${minutes}:${seconds}`;
      time--;

      if (minutes <= 0 && seconds <= 0) {
        minutes.innerHTML = "00";
        seconds.innerHTML = "00";
      }
      }
