New Boss on the Block Dash?

Hello! I am creating a custom array of buttons for my steering wheel currently, and i plan on dedicating a few buttons for using with RealDash

I am using arduino to convert my resistive buttons into individual outputs, and then these output signals will be wired into OneGauge Hub that I will assign to RealDash

When looking at New Boss on the Block, I would like to toggle between Trip info and Map, from my steering wheel buttons.

Can someone please guide me as to how many buttons/inputs i would need for this (assuming only 1?)
And , what action i would assign to my button input from OneGauge/Steering Wheel?

Thank you so much !
