How to use Python V4 Api with Azure?

questions = client.collections.create(
    name="Questions",
    vectorizer_config=wvcc.Configure.Vectorizer.text2vec_azure_openai(
        base_url= 'https://xxx.domain.com/',
        deployment_id="text-embedding-3-large",
        resource_name="xxx"
), 
    generative_config=wvcc.Configure.Generative.azure_openai(
        base_url= 'https://xxx.domain.com/',
        deployment_id="text-embedding-3-large",
        resource_name="xxx"
    )  # Ensure the `generative-openai` module is used for generative queries
)
