I guess this is included in our entra_auth_targets integration test, but annoying because it's a hard one to debug, and it used to only accept ml.azure.com....

Azure OpenAI (*.openai.azure.com) and AI Foundry (*.ai.azure.com).

Args:
endpoint (str): The Azure endpoint URL.

Returns:
str: The appropriate token scope for the endpoint.
- 'https://ml.azure.com/.default' for AI Foundry endpoints (*.ai.azure.com)
- 'https://cognitiveservices.azure.com/.default' for other Azure endpoints
str: The token scope 'https://cognitiveservices.azure.com/.default'.

Example:
>>> scope = get_default_azure_scope('https://myresource.openai.azure.com')
>>> # Returns 'https://cognitiveservices.azure.com/.default'
"""
try:
parsed_uri = urlparse(endpoint)
if parsed_uri.hostname and parsed_uri.hostname.lower().endswith(".ai.azure.com"):
return "https://ml.azure.com/.default"
except Exception:
pass

return "https://cognitiveservices.azure.com/.default"
