We have Office 365 groups created for various purposes, and as we roll out Power BI to more and more users within the organization, we are running into the issue that these groups show up in Power BI along with specific Power BI groups created for them. For example, Marketing has an Office 365 group created for them and this shouldn't be showing up in Power BI, but the app workspace should. They could potentially use the Office 365 group, but the BI team doesn't have any access to publish there.
In addition, there are groups which should never show up in Power BI. How can this be done?
