How to display the summary hierarchy in BigGantt

Question

I want to show a hierarchy of tasks with an "is contained in" relationship between them. The screenshot below is a screenshot of how I manually grouped the tasks after they were created. I want to create a task, attach "is contained in" to it, and have it automatically appear as [Hierarchy] in BigGantt.

The Configuration -> Gantt -> Column Views menu said there was a Hierarchy feature, so I looked for it, but couldn't find it. I need help.

[Not Hierarchy]

[Hierarchy]

I think what you are looking for can be found in the tab Tasks/Task Structure.
There you can activate (with the blue toggle) a link based task hierarchy.
