Hey, is there an example for using DAG-GNN to generate the DAG?

I'm trying to understand this awesome work, and have noticed that the example notebook only show pc, ges and lingam, I try to figure out the DAG-GNN repo, but it need a ground truth G to the input, just wanna know how do you get this and how to use the DAG-GNN.

Thanks.
