I've just inherited a Jira project and I'm quite new to Jira. I'm having trouble understanding how teams are managed. When I go to Project Settings > Access I can see a list of roles. This is a small list (much smaller than the team). One role in particular project:websquad looks like some group. It's not clickable and there doesn't seem to be any way to determine what it is or how to manage it. So I navigate to mycompany.atlassian.net/jira/people/search and search there, but returns no results. Seems to be not a team or a person.
I've also browsed around projects and pretty much everywhere that is reachable in Jira but I've no clue what is project:websquad
How does one find things in Jira?
