How to configure The Thevenin model as a second-order model

I noticed in the official documentation that the “number of rc elements” parameter of the Thevenin Model seems to indicate that this model can be configured as a second-order model.
However, I’m unsure how to set multiple RC parameters. I printed out the parameter list for this model, and it only includes R1 and C1. How can I set the values for R2 and C2?

There is an option you can pass to the model Thevenin({"number of rc elements": 2})

I know this parameter and have tried it, but when I print the parameter list of the model, there are still no R2 and C2 parameters

Ah sorry for the misunderstanding. The default parameter values are for a 1 RC pair model, you can add your own R2 and C2 parameters though. If you print model.parameters you will see which parameters the model expects
