Hi

My PS5 DualSense controller seems to be recognized by the game (as it defaults to joypad UI when it's connected and the left joystick works) but no button works. It seems to be fairly easy to fix with Unity, please consider adding support in an update (that's the only way to play the game for me as my french AZERTY keyboard doesn't make playing with the keyboard viable)

This is probably due to you not having set up the controller properly (this should be written somewhere but I don't think it is at the moment). You have to go to options > rebind controls and then set all the buttons in there. Also you might need drivers for the controller, I needed that for my HOTAS at least.
