Fabuia Mk3 2018 headlight adjustment continental driving

Have seen the previous post regarding the headlight adjustment on various cars including older Faba Mk3 but the adjstment mechanism appears different in my car - there is now a black lever which I assume moves the shutter to hide the kerb-side illumination, but it is not obvious how it works.

Vehicle is 2018 Fabia Mk3 with halogen projector lights.

Anyone have experience of DIY adjustment?

Thank you so much
