Hello, one thing I'm trying to do is create a outbound call assistant and what I was told to do was to use the Post - Create Assistant page on the API Doc: https://docs.vapi.ai/api-reference/assistants/create When trying to choose the transcriber and picking the provider or model all it does is copy instead of potentially adding it to the POST code. Do I have to manually add it in or is there something that I can click and add it automatically based off my preferences?
