I found what appears to be the correct Authoring REST API documentation (as of 06 November 2025):
https://learn.microsoft.com/en-us/rest/api/language/analyze-conversations-authoring/operation-groups?view=rest-language-analyze-conversations-authoring-2025-11-01
And I found it from this page (Azure AI Language REST API reference):
https://learn.microsoft.com/en-us/rest/api/language/
Here is one example (found on the Authoring API sub-pages):
Source: https://learn.microsoft.com/en-us/rest/api/language/analyze-conversations-authoring/conversation-authoring-trained-model/delete-trained-model?view=rest-language-analyze-conversations-authoring-2025-11-01&tabs=HTTP#code-try-0
DELETE {Endpoint}/language/authoring/analyze-conversations/projects/{projectName}/models/{trainedModelLabel}?api-version=2025-11-01
