Workspace and Office 365 Usergroups

Hi,

I have recently joined a company that is using PowerBI. They have intergrated office 365 and quite a few usergroups.

The problem I am finding is that many users can see the Workgroups that I have set up and usergroups that they are a member of, all in the PowerBI Workspace  pane.

 Is there a setting either in Power BI or 365 admin portal where only Workspaces can be shown and all Usergroups hidden?

Thanks
