Cannot find /libs/dam/cfm/models for Content Service
I follow the instruction "Installation on AEM 6.3 SP1" from Adobe Experience Manager Help | Getting Started with AEM Content Services - Part 1 - AEM Content Services Set up to setup content service. In part two, I don't see the "Content Fragment Models" under the Tool -> Asset. Goto CRXDE, Nor the models under the /libs/dam/cfm.
Does anyone know what additional package or configuration I need to do in order to see the "Content Fragment Models" under the Tool->Asset?
Thanks.
