Q: PS5 controller Adaptive trigger for PC , what's it supposed to do?

Q:
With patch 6.0 , support for the PS5 DualSense controller's 'adaptive triggers' for PC was added:

• In game, what is it supposed to do/add?
• for each/any of the answers to above, how are they supposed to be configured/enabled?
• Ideally, where is such documented officially?

Under 'System' I have chosen PS5 as the controller type. I have vibration enabled. I have sound coming out of the controller. I can feel vibration when walking and mounting etc but... I can't work out what on earth is supposed to be different about the triggers with support for 'adaptive triggers'. I understand that the principle is that the triggers can provided programmed, variable haptic feedback, but how this is suppoed to be used in the came I cannot work out.

Can anybody please help?

Thank you.

As one who's playing on PS5, the only use of the adaptive triggers i've found in game were with the "sniper" cutscenes.

That's pretty much it, the AT isn't possible to control, or use anywhere else in the game.
