The response of API "Get webinar participants reports" and the time

Hi there,

I have 2 questions about API, could you please tell me if you would know?

Is there any query parameters like participant’s ID which can be nominates the person at API “Get webinar participants reports”?
We can get all participants’ data as array when using “Get webinar participants reports”, but I’d like to get one specific participant’s data only. Is there any hidden options?

I’d like to get the datetime data as local time, not universal time. I see the data is universal time when retrieving from “Get webinar participants reports”.
I found below question, it seemed impossible 2 years ago. Is it now the same situation?
