Incidence matrix from ModelingToolkit.jl

Hi, I’ve just started using ModelingToolkit properly and am looking at doing some hybrid stochastic modelling. For my framework I need the stoichiometric matrix and reaction propensities. In the @mtkbuild output there is an incidence matrix shown.

So my question: is there a way to save this incidence matrix or access it after the model has been built?

It seems silly to have to completely redefine my model to build a stoichiometric matrix with reaction propensities when it seems like ModelingToolkit can access this kind of information.

Apologies if I’m being naive with the capabilities of this package…
Thanks!
