An organization I belong to uses MS Teams for meetings. I can join their meetings when I get an invitation, by clicking on the link they sent, but there's no option, while I'm in their meeting, for me to change my background. I also have a free account with MS Teams, which says it allows for a custom background, but I can't find a way to join the other meeting while signed in to my account.
Is there a way to activate the custom background while I'm in a meeting that someone else started, either while I'm signed in to my free account or not?
