DetachedInfo not showing any info

Probably I am not using this correctly so I would appreciate some clarification.

So, we have a new fresh file with instances coming from components that are published in one of our internal libraries. If any of these instances is detached, it becomes a frame, so I understand that Figma has not implemented any mechanism to trace back the owning component.

For me it just prints null
