Accessing Username on Run

I’m trying to access the username of who is running the repl to add dev tools; however, I can only access the owner. I want to be able to invite people to the repl and have features that only I can access.

Replit join link, if you want to run for yourself:
https://replit.com/@ashrit_lv/account?v=1

from os import environ

username = environ.get("REPL_OWNER")
print(username)

Thanks, Ashrit
