The modeling of groups is analogous to that of a path. Under Configuration, select "Pathbuilders" and then click "+ Add Path", even if it is a group. Then, after assigning the name for the group, select the Path Type "Group" from the dropdown menu below.
In contrast to a normal path, the modeling of a group does not end with a property, but with an entity. For the already known collection process to be captured on the object, the modeling is as follows:
S1 Collection object → N23i was collected by → S20 Collection process
