如何仅显示动态生成特定悬停div的工具提示

<div class="tooltip" data-tooltip="这是一个工具提示">悬停在我上面</div>

.tooltip {
  position: relative;
  display: inline-block;
  cursor: pointer;
}

.tooltip::after {
  content: attr(data-tooltip);
  position: absolute;
  background-color: #000;
  color: #fff;
  padding: 5px;
  border-radius: 5px;
  font-size: 12px;
  visibility: hidden;
  opacity: 0;
  transition: opacity 0.3s;
}

.tooltip:hover::after {
  visibility: visible;
  opacity: 1;
}

const tooltips = document.querySelectorAll('[data-tooltip]');

tooltips.forEach((tooltip) => {
  tooltip.addEventListener('mouseover', () => {
    const tooltipText = tooltip.getAttribute('data-tooltip');
    const tooltipElement = document.createElement('div');
    tooltipElement.classList.add('tooltip-content');
    tooltipElement.textContent = tooltipText;
    tooltip.appendChild(tooltipElement);
  });

  tooltip.addEventListener('mouseout', () => {
    const tooltipContent = tooltip.querySelector('.tooltip-content');
    tooltip.removeChild(tooltipContent);
  });
});
