What is the equivalent of the following in Julia?

[https://support.gurobi.com/hc/en-us/articles/15656630439441-How-do-I-use-compute-IIS-to-find-a-subset-of-constraints-that-are-causing-model-infeasibility](https://support.gurobi.com/hc/en-us/articles/15656630439441-How-do-I-use-compute-IIS-to-find-a-subset-of-constraints-that-are-causing-model-infeasibility)

I understand I should be using direct\_model(), but I am having trouble finding documentation of what the equivalents are in Julia.

Let me knoe if you still have questions after reading. Perhaps we need a proper tutorial about this.
