Making M1 - M2 buttons on retrofitted steering wheels usable

[BeepBoop321]

Hello, and welcome to another episode of "Let's overcomplicate something that can be achieved in seconds manually".
The other day I was on facebook and saw a video of someone that had the m1-m2 buttons on their retrofitted steering wheel working.
This gentleman did not leave instructions on how he achieved this, but what can be seen from the video is that once he selects the 'm1' button, it appears to toggle between sport, sport plus, and sport individual.
Now that we know this is possible, I wanted to start a thread to see if we can brainstorm ideas and solutions on how to do this.
