Retrofit the ESP Button from GLC 2016 into S205 2016

[Faultier]

I have a 2016 S205 and I installed the ESP button from an identical GLC. I can disable the ESP via the instrument cluster, but I would like to activate the button. I already looked up the code in the VGSNAG2 manager, but I don't know how to activate the button. I didn't find anything in the head unit coding. Maybe someone can give me some advice.
