I want to use the prediction API on a model I have already trained and published online. I understand that in this Quickstart Tutorial for C# that you can create a project and train a model with code. When you create this project through code, it creates an object of type Project where you can find the project ID. Is there any way to get an object of type Project from a pre-existing project? If not, where can I find the "project ID" or "publishedModelName" of my pre-existing project so I can detect with it through API calls?
