;; One Wayland, Zoom needs two extra environment variables to be set:
;; - XDG_CURRENT_DESKTOP=GNOME (to get past the refusal to try sharing the screen)
;; - QT_QPA_PLATFORM= (since QT_QPA_PLATFORM=wayland makes zoom fail to start)
;; The following package definition patches it to set those variables.
