Room tick for Guest (old, not shown)
What it is
A tick box in the Guest column of an old Rooms & who may use them table. In this configurator version the code that draws it is never called, so it does not appear on any screen.
What to enter
Nothing. It is not shown.
What it changes
Nothing, because it is not shown. (It would decide whether the shared guest PIN shows the room after the next deploy.)
If it goes wrong
Room access is set elsewhere; see the help for the Users and Rooms steps.
