Nextion screen buttons to trigger events

Hi all,

I have been working on a project where I want to use my nextion display to have buttons for general navigation using keyboard mapping, when games aren't running. I have created a custom dash, but cant get simhub to recognise the button being pressed.

my initial question is; is this even possible? I cant find any examples where this is being done so I am wondering if I'm wasting my time experimenting.
