You can see the different groups in the detailed view of the objects. Double-click on an object to open the detailed view.
You can arrange the groups in different order - this is how it works:
Go to "Settings", "Field definition (objects)"
You can see which group a field is assigned to in the Group column.
Let us now assume, as an example, that the additional data group should be arranged above the base data group:
Click on a field with the additional group and drag it over the top field with the master data group
Now the additional group is displayed as the top group in the detailed view of the objects
