I have an API key and an Azure endpoint URL. I have entered them both in the settings. Is there a particular name I should name the model I have deployed in my Azure OpenAI? I am able to interact with it in my playground in Azure, so I think it is deployed correctly. When I open Altair CoPilot, it simply says "Chat service is not available. (Altair CoPilot requires a valid API key to be set)" even though I have entered the appropriate values in the settings.
