I was using LUIS previously and using api, I would upload my json file containing intents, entities and utterances to my project. Now as LUIS is expired and Microsoft has replaced it with CLU(Conversational Language Understanding). I cannot find any API to upload my data(utterances) to CLU project. I want to know what is alternative to this, I want to automate the process of uploading my utterances to CLU.
I have gone through all the documentation of CLU authoring API but couldn't find any api to upload utterances.
