Communities tab in Teams

Hi there 

I've recently had the Communities tab pop up in my Teams alongside the Teams and Channels tab. 

No one else in my organisation can see this yet and we aren't sure why. I know it's being rolled out on a timeline but I was also wondering if it might be because I'm the only one in the org who has an Microsoft Viva Employee Communications and Communities licence?

Does anyone have any insights into this?

We'd like to make a bit of a roll out plan once this appears in our colleagues Team's set ups.
