Hey Muralikrishnan,
I believe what you're asking for is transcripts organized by user? This isn't available out of the box from what I can find, however extracting, doing some transformation and leveraging Power BI will potentially give you what you are asking about. Please ensure you've reviewed the Learn articles on analytics, transcripts and such. Do some hard thought on if you really need to build this, as the copilot platform changes by the hour, and deeper insights are likely something we can expect.
