How to Display Omniverse Scenes on My Custom Website and Control the Camera and Models

I am a beginner with Omniverse and have followed the tutorial by Ashley on YouTube (https://www.youtube.com/watch?v=0TDz0vjIgGQ&list=PLPR2h_elPvVKH9HLtdgfXNUxGeN6QAlc7&index=2&t=3299s). I successfully rendered the Omniverse scene on my webpage. However, I have a few additional requirements that I would like to achieve:

  1. How can I control the camera’s viewpoint through code to focus on my model (similar to pressing “F” on the model in Omniverse)?
  2. I want multiple users to be able to open the webpage and view the Omniverse scene simultaneously. Currently, only one person can view it; if another person opens the webpage, the screen is black.

I would appreciate a detailed tutorial, preferably with step-by-step instructions, to help me achieve these requirements. Video tutorials would be especially helpful.
