Drill-throughs modal not shown to non-admin users

I have a collection that have a dashboard, questions and models.
When I (an Admin) view a model-based question in the dashboard, I can hover with my cursor on the question, click and see the drill-throughs modal.

When others, who have a view permission on the collection (without any data access permissions), do the same - the drill-through modal do not pop up when they click on the graph.

What can be the reason?

Thanks!
