MG ZS (Gen 1) - am I missing the rear wiper spray nozzle?

[ZSinthecountry]

Hi all,
The cover came off my rear wiper (2021 MG ZS EV) and since refitting it, the water spray comes straight out the spindle (so I know it's not blocked) & dribbles down the rear boot when cover is back on.

I suspect the actual sprayer head has been snapped off and lost but struggling to find the right one - does anyone have a photo or part number?

Here is what is looks like currently


I suspect the centre pin is missing something like this?

Thanks!
