How to remove box-shadow from center-controls?

How to remove drop-shadow from the parent SHADOW element "center-controls"?

<div slot="centered-chrome" class="center-controls pre-playback">
  <media-play-button part="center play button pre-play" tabindex="0" role="button" aria-label="play" mediapaused="">
    <!-- SVG Icon -->
  </media-play-button>
</div>

I tried CSS Parts - but it only targets media-play-button part="center play button pre-play"::

mux-player::part(center play button) {
  shadow: none;
  filter: none;
}
