Looks good! One thing though. It seems that fetchDataForManagerView and fetchDataForRegularView will be very similiar, and it would be nice to avoid a lot of duplicate code.

I didn't realize the similarities. Refactoring completed.

Did you remember to add the Group as a default group as well @Petterandre ?
