I have a collectionView with drag-drop functionality. However, I want to avoid cell shadow on dragging. I found some solutions using dragPreviewParametersForItemAt function, but I am not sure what parameters to return.

func collectionView(_ collectionView: UICollectionView, dragPreviewParametersForItemAt indexPath: IndexPath) -> UIDragPreviewParameters? {
    guard let cell = collectionView.cellForItem(at: indexPath) as? UICollectionViewCell else {
        return nil
    }
    let previewParameters = UIDragPreviewParameters()
    previewParameters.visiblePath = UIBezierPath(rect: cell.frame)
    if #available(iOS 14.0, *) {
        previewParameters.shadowPath = UIBezierPath(rect: .zero)
    }
    return previewParameters
}
