Help? Mercedes A160 Window Buttons Removal

[paris]

Hi, sorry for making a thread for such question but I need some knowledge if anybody done such thing.. My mother-in-law's Merc A160 has had some coke spilled over the window buttons. After a day, they stopped working and i want to remove them to clean them in my ultrasonic cleaner. How do you get them out? Pop out or do I have to remove the centre console to access them from below?

Thanks thanks!!!
