Video Set-Up Prior to a meeting

[KellyMiller1963]

Is there a setting that will allow me to set up my video and adjust everything (lighting, background, my HAIR, etc...) PRIOR to being added to the meeting.  I had this feature in the past, but when I purchased a new computer, I no longer have this.  I am added to a meeting with my profile picture showing. Then I have to turn on my video and adjust everything when I'm already in the meeting.  I would prefer to see myself and my background BEFORE going into the Zoom meeting.  How can I make this happen?
