A visualization adapter license for PDM Essentials

We are using Windchill PDM Essentials.

To publishing the visualized model of products it use a Pro/E License.

But as I read a visualization adapter license on PDM Essentials is included(or asked it to PTC with no charge).

The partner for us said that license is not, a visualization adapter only is included which used Pro/E license to publhsing.

I don't know what it is right.
