Exception: The demo llm-rag-chatbot doesn't exist.

[xiinex]

Hello,
when I try to bring the demo environment (LLM Chatbot With Retrieval Augmented Generation (RAG) and DBRX) into my Databricks workspace, I get the following error: Exception: The demo llm-rag-chatbot doesn't exist.

I execute the following code:

%pip install dbdemos

dbutils.library.restartPython()

import dbdemos

dbdemos.install('llm-rag-chatbot')

Can someone explain to me why this is the case? Does this demo environment still exist or can it be found under a different name?
Many thanks in advance!
