Currently additional users can only be added to conferences by sending links, invitations or callouts. I ask for a much easier way. Just searching for an user by his name (for internals) or email address (externals) and than adding him to the conference. The added user gets the pop up for a video call and can join the conference. No need for sending emails, links etc. Would be really helpful in the daily business when fast discussions and decissions are necesary.
