How to Contact a Private User HELP ASAP

Users in the tasks I am supposed to do are all indicated as Private Users except for my boss. I am supposed to email one of them for the work instructions; however, I am unable to make a “team chat” with them using the tips I have gathered from another thread. Note that I was not assigned the task, but mentioned in the comment section to work on it together with a private user, and with the help of another private user.

Please help. I have been trying to navigate the site since yesterday.
