How to use the @build-tracker/comparator.CellType.ARTIFACT function in @build-tracker/comparator

_renderCell = (cell: BT$BodyCellType, columnIndex: number, artifactName: string, isHovered: boolean) => {
    const { color, isActive, onCellClick, onToggleArtifact, valueType } = this.props;
    const hoverColor = hsl(color);
    hoverColor.s = 0.7;
    hoverColor.l = 0.95;

    switch (cell && cell.type) {
      case CellType.ARTIFACT:
        return (
          
        );
      case CellType.DELTA: {
        // $FlowFixMe
        const deltaCell = (cell: BT$DeltaCellType);
        return (

    cell: BT$BodyCellType,
    cellIndex: number,
    rowIndex?: number,
    cellText?: string,
    style?: mixed
  ) => {

        );
      case CellType.TEXT:
