remove the original attendee who shows up

remove the original attendee who shows up firstly on the stage.

If you refer below KB to sync your stage to attendees,you will find there is another attendee showing up on the stage except the host.If Cu want to lock the stage,they can't remove this attendee from stage.This is very inconvenience especially when host wants to expand their vieo to the attendees. Is it possible to remove this attendee for the host?
