AzureOpenAIService Custom Connector - it's working but the parameters don't seem to effect the response

[dibbkd]

I've got the AzureOpenAIService custom connector installed and it works, but some of the parameters in ChatCompletion don't seem to effect the response. For example, for "system_instruction", you should be able to say "you are a comedian", or "you are Shakespear" and the response would be reflected in that.

I've got the connector in a Power App, and have a fields to input the settings, then a button submit like this:

Set(varResponse3, AzureOpenAIService.ChatCompletion("deployment-gpt-35-turbo","2023-03-15-preview",{messages:{role:"user",content:TextInputChatGPTPrompt_1.Text},
system_instruction:TextInputSystemInstruction.Text, max_tokens:TextInputMaxTokens.Text, temperature:TextInputTemperature.Text,
presence_penalty:TextInputPresence_penalty.Text, frequency_penalty:TextInputFrequency_penalty.Text, top_p:TextInputTop_p.Text, n:TextInputN.Text, stop:TextInputStop.Text,
user_message:TextInputUserMessage.Text}))

Then I display the "answer" like this in a text box:
varResponse3.answer

The last issue I'm having is that I can never get any results returned for the usage, it's just blank.
varResponse3.'raw-result'.usage.prompt_tokens
varResponse3.'raw-result'.usage.completion_tokens
varResponse3.'raw-result'.usage.total_tokens

Any suggestions?
