Usage of an object
It can be helpful to know where it used an object in the model.
In the below example, we want to know where it used the "internal_activity":
1/ Select the object and right click Report > Usage:

2/ All the elements using the selected object are listed in Assistance:

In the example, internal_activity is using by two User Stories. By double clicking on an element, you will open it.
You can also do that with flows, variables, states...
