How to Change VirtualButton Sensitivity at runtime

Hey all, sorry if this is a repost, im relatively new to working with Vuforia.

I was just wondering how do you change the button sensitivity of a virtual button created at runtime.

I can see theres a function 'bool virtualButton.UpdateSensitivity()' but im not sure how to use this. When looking at the API for the function it just says Update Sensitivity in Native. I have no idea what this means or how to use it. There are no parameters to send in to change between "LOW" "MEDIUM" and "HIGH".

I can easily change the sensitivity of a virtual button from editor, but im dynamically creating decks from multiple databases so doing it via editor isnt realistic.

Any help with this would be great! Thanks!
