Proper ventilation in the staircase of a multi-family house? Electric window on the upper floor

Good day.
I hope I am in the right forum here.

How do you properly ventilate the stairwell in a new multi-family house?
In the attic floor ([DG]) (from ground floor [EG], upper floor [OG]) there is a window that can be opened electrically.
This means it can only be opened with a special key.
If this is then closed (which is usually always the case), the air in the stairwell becomes stagnant.
To avoid mold and to have better air in the stairwell, the upper window would need to be opened so that a draft can be created between the entrance door and the upper floor.
But this window (fire protection window) cannot be opened that easily.

Question:
Assuming one opens the upper fire protection window to create a draft, would this violate any regulation?
Or why is such a window equipped with an electric opener?
Would there be any problems with the fire protection insurance if the window is kept open?
The draft would ventilate the stairwell well.

Thank you very much!

Do you have a property management company?

Best regards in brief

No, why should it?

But this window (fire protection window) cannot be opened that easily.

In case of fire, this window should (must? state building code?) open automatically. Then smoke and heat can escape and the escape route staircase is (hopefully) usable. There are minimum requirements for the free cross-section of the window. Ventilation is independent of this; it just should not let rain in.
