The integration with Power BI is a little clunky.
Adding an embedded PBI Report to a team does not get the members of that team permissions to view the content.
Instead, even without Pro licences and when using premium capacities, users need to be manually added to the corresponding report workspace.
Could there be a way of assuming view only membership for anyone that is a member of the relevant team instead?
Alternatively, use any premium capacity that has been configured like other embedded options do.
