How to leave a teams meeting series from a teams device (eg: poly x30, neat bar,board, surface hub)

Hi, just checking on this issue.

 

if someone creates a teams meeting series and invite some rooms/devices (eg: surface hub, neat bar, neat board, mtr room (eg: logitech tap, or creston uc engine based). how can they leave the meeting  series without having the meeting organizer remove them? 

logging into teams.microsoft.com may not be an option (cos its asking for either sspr or 2fa and i don't think i should set those up).
