Who to contact to re-join Zulip chat

[Pranav Setpal]

If you deactivate your zulip chat account for sagemath, you can no longer re-join with contacting the organization administrator.

I have been trying to find the organization admin, however, I could not find any information on who to contact. Can anyone please direct me to the same?
