I have been given access to the Cohere reranker through my companies Azure AI studio. I see that I can do inference in LlamaIndex with LLMs in Azure, but can I use the a reranking model in Azure as a node postprocessor, as I would do using from 'llama_index.postprocessor.cohere_rerank import CohereRerank'? I saw a github support inquiry mentioned using 'from llama_index.core.postprocessor import AzureRerank' but it doesn't work. Maybe it was an llm hallucination...
