@guidari just want to double check this is no longer needed? Maybe we should add support for onChange to be logged to the actions pane in one of the storybook stories so this is testable in the deploy preview?

[guidari]

Hey @tay1orjones we don't need that anymore because we are passing here:

} = useSelection({
    disabled,
    initialSelectedItems,
    onChange,
    selectedItems: selected,
  });

I added to the storybook
