How to get response curves seperately for each spending

[bahadir-uyarer]

I am using robynpy==0.3.6 in python edition. My python version is 3.11. I am following the tutorial1_src to build my MMM with my own data where I am using several different parameters but the skelaton is same with the tutorial. I am trying to build response curves separately for each spending channel but could not manage to handle it. Could you please guide me in the context of aforementioned tutorial.
