CloseVanillaMenu
Since: IVPrismaUI6
virtual bool CloseVanillaMenu(const char* menuName) noexcept = 0;
Closes a vanilla menu immediately, by MENU_NAME.
This is a one-shot action - it does not affect whether that menu can open again in the future.
Combine with SuppressVanillaMenu(name, true) first if you also want it to stay closed going
forward.
