Animating ball around SVG path in React-Native

I am trying to animate a ball around an SVG path in React-Native and am not quite sure how to go about doing it, the SVG path is a pill shape.

Here is my code so far,

<View style={styles.container}>
  <Svg height="500" width="400">
    <Path
      d="M80 340 A100 100 0 0 0 320 340 v-200 A100 100 0 0 0 80 140 v200"
      fill="none"
      stroke="#eaeaea"
      strokeWidth="16"
    />
    <Circle cx="320" cy="160" r="16" fill="#512468" />
  </Svg>
</View>

And here is a visual:
