How to use the @tensorflow-models/body-pix.blurBodyPart function in @tensorflow-models/body-pix

case 'pixelation':
            const pixelCellWidth = 10.0;

            bodyPix.drawPixelatedMask(
                canvas, state.video, coloredPartImageData,
                guiState.partMap.opacity, maskBlurAmount, flipHorizontally,
                pixelCellWidth);
            break;
          case 'partMap':
            bodyPix.drawMask(
                canvas, state.video, coloredPartImageData, guiState.opacity,
                maskBlurAmount, flipHorizontally);
            break;
          case 'blurBodyPart':
            const blurBodyPartIds = [0, 1];
            bodyPix.blurBodyPart(
                canvas, state.video, multiPersonPartSegmentation,
                blurBodyPartIds, guiState.partMap.blurBodyPartAmount,
                guiState.partMap.edgeBlurAmount, flipHorizontally);
        }
        drawPoses(multiPersonPartSegmentation, flipHorizontally, ctx);
        break;
      default:
        break;
    }

    // End monitoring code for frames per second
    stats.end();

    requestAnimationFrame(bodySegmentationFrame);
  }
