The EVCC on the ZS EV is located on the N/S ( passengers side ) of the car.
If you first look towards the rear of the 12 volt battery, then look down at the chassis rail, then you will see the unit bolted to that rail.
You should be able to check the part number.
We had one of the early ZS EV Gen2 models and it came with the capability to conduct V2L and it worked from day 1.
However, it would only allow discharge to continue, with the car unlocked.
As soon as you locked the car, it stopped discharging instantly.
This was corrected by a software update at the point of the first service by the lads at Chorley

.
The later models had the update applied I believe.
The majority of ZS EV’s that failed to perform V2L had the wrong EVCC fitted at the factory and this was corrected FOC by SOME dealers, others wanted paying for it !.
