The options reflect the amenities you have available in your organisation, and after they are created, you can link them to rooms and desks.
Log in to the BrightBooking portal with your manager account, and choose Settings > Options.
Now add a new option with the '+' button, or select an existing one to edit.
Each option has a name, and can be given an icon from the predefined set of icons.
Lastly you can configure if the option is a room or desk specific option.
