I can’t understand why buttons don’t react on click. trying to make basketball counter on plain JS

Here is piece of HTML and script file there is 3 buttons, each should increase counter on 1,2,3. But this doesn’t work. Plain JS.

const scoreEl = document.querySelectorAll('.score-title');

let count = 0;

function increment() {
  count = count + 1;
  scoreEl.textContent = count;
}

function twoIncrement() {
  count += 2;
  scoreEl.textContent = count;
}

function threeIncrement() {
  count += 3;
  scoreEl.textContent = count;
}

<div class="score">
  <div class="score-title">0</div>
</div>

<div class="button-container">
  <button onclick="increment()" class="btn-score">+1</button>
  <button onclick="twoIncrement()" class="btn-score">+2</button>
  <button onclick="threeIncrement()" class="btn-score">+3</button>
</div>
</div>
