How to get annotations into json file

Hey,
sorry if I am missing something in the documentation, but I would like to know how can I convert the annotation results for images into json file with coordinates (something like coco file) so that I can work with the annotations further?
Thanks a lot!

The issue names no file, test, or entry point. Start by reviewing the repository's example notebooks and the annotation results they produce, then determine what documentation is needed for exporting image coordinates to a COCO-like JSON file. Done means a clear, reproducible documented path.
