Can not find the communications section in Sophos Central Phish Threat

Hello, 

I have an active free trial of Sophos Central Phish Threat and this article says that I can write my own newsletters or modify an existing newsletter within a section called "Communications".

I'd like to try this, but I can't find that section on my admin portal.

Here is how it actually looks:

I also asked a colleague of mine who has a phish threat full license, and she said she doesn't has that section available either.

Is there an specific license for newsletters? If so, which one is it?

I would really like to try this feature.

Thanks in advance...
