I am wondering if this can be just replaced with state, and props.allowDownload can be used in the useCallback?

I think using props.allowDownload in useCallback dependencies will trigger change definition for method setDownloadButtonVisibility not shouldShowDownloadButton value.

but we can use it in useEffect.

const [shouldShowDownloadButton, setShouldShowDownloadButton] = React.useState(props.allowDownload);

useEffect(() => {
  if (shouldShowDownloadButton === props.allowDownload) {
      return;
  }
  setShouldShowDownloadButton(props.allowDownload);
}, [props.allowDownload]);

what do you think? @mananjadhav
