Data sharing across personal and work profile Google Calendar apps

Hi there to the community.

I am setting up data sharing across the personal Google Calendar app, and the work profile Google Calendar app. Currently, I am testing the solution with the Test DPC app, just to understand behaviour and settings of the split environment.
I connected Google Calendar apps, so I can view events from the personal calendar in the work profile app, together with work events.
However I can't get the opposite, so work events are not visible from the personal app, despite apps connection. Of course, this is very confusing.

How can I fix the issue?

Thanks a lot.
