How to enable the "Customize this Space to help your team settle in." box in Jira Backlog view?

[Tiago Cardoso]

I run different projects for different clients. I've noticed that in at least one of them I got an option to enable a few details about the team in the backlog view, whereas in other one I don't. 

What's the criteria to enable / disable it? Or am I stumbling in an A/B test?

This seems to be a neat functionality to remind team about Team Agreements.

I'm admin in both projects.

I'm admin in both boards.

Kanban is used in both boards.
