Difficulties when using iframe on a website

I want to use the jitsi iframe on a website, I need to configure a series of features that are not common in video calls … I need to play the role of moderator, mutating and giving the floor to different users. I’m having some difficulties due to lack of information in the documentation, I’m using javascript. Every help is welcome.

Below are some specific problems that I don’t know how to solve:
-Change the focus of all users remotely
-Change the status (microphone and camera) of all users remotely
