Langgraph deployment questions in the langchain-academy tutorial (cloud via LangSmith).

[Incantatoric]

Hi, I have a few questions while following the langchain-academy introduction. I had a few problems with Module 1 deployment. In particular,

1. In the introduction video here, Langgraph Studio shows the url which is then used within the jupyter notebook code. I am on Linux and I am using the web version of Langgraph Studio, and it does not show me the url (I guess this is to be expected since I am not using Docker). Is there any way that I could still run the code to see how deployment works?

2. The same video then introduces deployment to Cloud via LangSmith. I am following the linked page here and when I go to LangSmith->LangGraph Platform, it seems like I could start accessing it starting from Plus account. The top right corner does not have '+New Deployment' panel but only has 'LangGraph Studio' and I am not sure if it is relevant in keep working on the tutorial. Is there any way that I could try the deployment with my current free LangSmith account?

3. If I cannot proceed to learn more about deployment, what is the recommend way to test it? Plus account costs $40 per month which is too hefty without having the opportunity to test it in the first hand. Developer account seems free but it seems like it does not offer cloud deployment.
