Citigo e iV Style - switch for the electric side mirrors stopped working

Hi everyone! 😊
I’m Alessandro, writing from Italy. I recently became the happy owner of a Citigo e iV Style (used one). I really like it and it’s been great so far.

Unfortunately, a few days ago the switch for the electric side mirrors stopped working. I took it to a local auto electrician, but he refused to touch it because he said replacing that switch could cause errors in the car’s control unit.

Do you think he’s right? Should I go directly to a Škoda service center instead?
And does anyone happen to know the part number for that switch?

Thanks a lot to anyone who can help! 🙏
