Guns on the Lancaster Bomber from the WW2 Pack don't work

[Gamebreaks]

Describe the bug
I'm not certain whether or not this is a bug or missing feature but it seems more like a bug so I'm labelling it as that. The Primary Vehicle Interact key, which will normally fire the guns on planes and jets, doesn't do anything, despite there being guns on the vehicle. It doesn't work regardless of what seat I'm in, even though they can be aimed when using the seats behind the guns. The Secondary Vehicle Interact key does drop bombs, but the guns simply don't fire, and when opening the vehicle menu, the Guns option is greyed out, so I can't put ammo inside. Would be amazing to see them able to be fired by passengers in the correct seat, just imagine flying through an area full of enemies and having your friend in a gunner seat aiming and firing at all the enemies.

To Reproduce
Steps to reproduce the behaviour:

1. Enter a Lancaster Bomber in a gunner seat.
2. Open the vehicle menu.
3. The guns option will be greyed out.

Expected behaviour
I expected the turrets, which can be aimed if you're in the seat behind them, to also be able to be loaded and fired at enemies via the Primary Vehicle Interact key.

Screenshots
Turrets can be aimed but not fired
Guns option is greyed out
