Using XR Hand Gestures as Input Action Bindings?

I’ve been experimenting with the pre-release XR Hands package (1.4.0-pre.1), and I’m wondering if the Gestures can be used as bindings for input actions.
I know it’s in pre-release and everything is still in the works, but it would make sense to have gestures integrate into bindings, or at least allow the unity event to trigger an input action, as if it is were a binding.

Alternatively, if there is no way or no plans to integrate XR Hand Gestures into Input Actions (for whatever technical reason), I will just script a parallel custom input system to be able to trigger game actions like grabbing and shooting.
…Unless someone else found a better way of translating hand gestures to input actions that I’m not considering?
