How to embed fullsized AI Human using iframe

How to embed full sized AI human using iframe for unity project.

What I am trying to achieve is, I have AI human URL shared by client, which I need to integrate in to a Unity space where this AI human will be acting as a interactive kiosk, is there any step by step guide, if so can you share them

also how to access the Unity SDK, if I can access the unity SDK, I can directly integrate the deepbrain AI Human in to unity directly instead of iframe.
