Where to find the user id for a given annotation

[mickaeltardy]

Hello.

This was puzzling me for a while and I'm unable to find information in documentation or in git.

How one can know who (which user) created a given annotation? I have a somewhat relaxed use of CVAT, so many users may access the same task and put labels on it.
However, it also stands for a common use with users explicitly assigned to the tasks. I looked in the database and was unable to find any information. Different types of export do not contain info neither. Checked cvat, datumaro, labelme. The latter has username field empty.

Any suggestions?
Thanks
