Hi @dnsmnds ,

Thanks for opening this issue! We appreciate your feedback regarding the People feature endpoints. While direct support for these endpoints is not currently implemented in this SDK, we will take this into consideration for future updates. We'll evaluate its feasibility and plan accordingly.

Best regards, Tamás Juhász
