Problem While animating an svg point using tranform translate X

I’m trying to make a simple animation using translate X on a segment of my svg (while hover on the element). This is my code:

<html>
<style>
  .big-dot:hover {
    transform: translateX(20px);
    animation-duration: 1s;
    transition: all 1.5s linear;
    display: inline-block;
  }
</style>

<body>
  <svg id="Component_31_4" data-name="Component 31 – 4" xmlns="http://www.w3.org/2000/svg" width="42.534"
    height="49.111" viewBox="0 0 42.534 49.111">

    <g id="icon_navigation_chevron_right_24px" data-name="icon/navigation/chevron_right_24px"
      transform="translate(0 8.696)">
      <rect id="Boundary" width="24" height="24" transform="translate(13.423 11.72)" fill="none" />
      <path id="_Color" data-name=" ↳Color" d="M3.957,0,2.371,1.81,17.634,16.86,2.733,31.7,3.957,33.72,20.794,16.86Z"
        transform="translate(-2.371)" fill="#181e41" />
    </g>
    <g id="Group_3463" data-name="Group 3463" transform="translate(-780.577 -5591.11)">

          transform="translate(16.303 49.875) rotate(-45)" fill="#e05037" />

            fill="#377caa" />
        </g>
      </g>
    </g>
  </svg>
</body>

</html>

While hovering, the dot is doing a move on the Y axis instead and disappear. How Shall i tackle this? Also, is there a way I could use gsap to animate this considering this svg is inside a css class on a backround image ? Thanks
