No offence intended but why buy a Tesla charger for a non-Tesla car? Tesla are known for having propriety standards and therefore not normally compatible with other EVs. See this for instance from Smart Home Charge website https://www.smarthomecharge.co.uk/chargers/tesla/tesla-wall-connector/#:~:text=NOTE%3A this charger only supports,accessory for your Tesla vehicle.&text=Perfect if you have more,2.5m and 7.5m.
Also, why go for a 22KW charger for a Citigo that is only capable 7.2KW AC charging, unless you have another EV capable of faster charging?
