Project For the Web Connector - PWA?

Hi, I'm trying to connect the tasks from my initiatives automatically using the Project For the Web Connector.

Does anyone know if I can use the same connector to connect to my PWA (Project Web App) instance? At this time, some of our projects in my organization are managed via PWA. 

So I wonder if there is an environment permission in PWA to be allowed to I can select in the connector? I can see all my projects from Project Online just fine, just the ones hosted in PWA are missing.

If there is another channel where I can ask this question or get support, please let me know.
