Segmentation is stored in a 4D nrrd file with a couple of custom fields to store additional metadata - see detailed description [here](https://apidocs.slicer.org/master/classvtkMRMLSegmentationStorageNode.html).

You can use any nrrd reader that is capable to read 4D files. If your software cannot read such files then you can export to 3D labelmap (nrrd file) + color table (text file) and read those.
