Check user's last access

Hi, I am currently trying to get the information about a user’s last access of my gitlab instance. I.e., I know the last and current_sign_in_at fields but they don’t necessarily show the last time a person actually accessed gitlab.

I was wondering, could I use the updated_at field to get the desired information or is there a different parameter for that?

Thanks in advance!

From the users API: Users API | GitLab there is last_activity_on.
