Adjust slot type washer jet nozzles

[Dracoro]

Anyone know how to do this?
In the old days, 2 round holes and a pin and job done.

Now I have the single rectangular “slit” hole type that 2 sprays come out of.

However I cannot seem to adjust them. Tried pin and small flat blade screwdriver but doesn’t seem to adjust.

Are they actually no. Adjustable or am I missing the technique?

Seems same type of nozzle on both my Avensis and Cayman.

Mine adjust with an allen/hex key, have a look for a small hole near the washer jet. This will move the spray of water up or down depending which way you turn it.

Can’t see a hex/Allen anywhere.

Pics attached (black=Avensis, Silver=Cayman btw)

Anyone, can’t believe there’s no way of adjusting them….
