I am trying to run the same code as in the official github repo for the ScenTrees package (GitHub - aloispichler/ScenTrees.jl: Julia Package for Generating Scenario Trees and Scenario Lattices for Multistage Stochastic Optimization). This code is the following:

`using ScenTrees`

`gstree = tree_approximation(Tree([1,2,2,2],1),gaussian_path1D,100000,2,2);`

`tree_plot(gstree)`

I have added the ScenTrees package to my environment, but it seems like the functions defined in the package is not accessible. I get the following error:

I am new to Julia, so any guidance here would be much appreciated:)
