How to plot the tree of a Light GBM .joblib model?

Question

I'm very new to Machine Learning! My problem concern a model created with LighGBM. I'm not the creator of this model, so I want to see the tree that this model generates. The model is in the format .joblib, and I want to know as much information as possible of it. On the LighGBMclassifier Documentation i don't find anything that can solve my problem. Thanks to the code below, I only know the number of classes.

model = joblib.load("*.joblib.dat")
model.classes_

Output:

array([0, 1])

I want to know the number of rows, the rules and if it's possible, even the plot of the tree. Thank you all!

When you can not find something in the LightGBM documentation, look for it at XGBoost documentation. LightGBM documentation has loss of missing features that the framework has actually in it.
