Smart View access for non-power users

Summary

How to grant users and viewers access to PCM data within Smart View?

Content

We are rolling out our completed PCM implementation to our larger team, and trying to grant access to a group of individuals who should be able to view data via Smart View, but shouldn't have the ability to write rules in PCM, run the application, etc.

We have tried granting these users both the "User" and "Viewer" roles within My Services, but then when connecting via Smart View they only see "#No Access" in each cell where data should be returned. Does anyone know how we can grant users read-only access to the data in the cube while not giving them admin or power user rights?
