Error Message:
I've been using Azure AI Studio and Azure OpenAI Studio for some time, and I'm currently working on a RAG (Retrieval-Augmented Generation) implementation using Prompt Flow. I've run into an issue where, in Azure AI Studio's Prompt Flow, the option to connect to deployed models using the "deployment name" (as shown in the official Microsoft documentation, specifically in step 8) has been replaced by "model."
Due to this change, I'm unable to connect to my deployed models or use the models listed on the portal
