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

personOrPersonPartSegmentation.forEach(personSegmentation => {
      let pose = personSegmentation.pose;
      if (flipHorizontally) {
        pose = bodyPix.flipPoseHorizontal(pose, personSegmentation.width);
      }
      drawKeypoints(pose.keypoints, 0.1, ctx);
      drawSkeleton(pose.keypoints, 0.1, ctx);
    });
  } else {

personOrPersonPartSegmentation.allPoses.forEach(pose => {
      if (flipHorizontally) {
        pose = bodyPix.flipPoseHorizontal(
            pose, personOrPersonPartSegmentation.width);
      }
      drawKeypoints(pose.keypoints, 0.1, ctx);
      drawSkeleton(pose.keypoints, 0.1, ctx);
    })
  }
