Can coworkers calendar entries appear in app aswell?

Im trying to have our our coworkers calendar event that has been added onto the main business calendar show up in the hangouts. Anything done on from me on the main calender works perfectly with this app. Everyone in our Co has full permissions to add events to the main company calendar.
When I was using the google calender app (from google) they it would show up all the events added by coworkers onto the main calendar. It would show up also even if they only added the event on their own company designated calender to them.

I tried all sorts of variations and Im now out of ideas….. So Im just wondering if its something wrong being done on my side or its something that this app currently does not support?

A workaround could be just to give all the workers my login though obviously that would not be ideal.

Love the app!!!

Many Thanks ??
