Dynamics CRM Connector missing for Office 365 Groups Integration

I'm trying to kick the tires of Office 365 Groups and CRM Online integration, by following the documentation from Microsoft here: https://technet.microsoft.com/en-us/library/dn896591.aspx

The list of available connectors, however, seems to be missing the "Dynamics CRM Online" connector (I could swear it was there just a couple of weeks ago!). Does anyone know where it went, why it's not there, how to get it, or when it's coming back?

Thanks in advance!
