Removing a cistern lid with Geberit Twico 1 button Australia and NZ

[@davidjackson4843]

I just moved in to a new apartment. The toilet button is just like the one seen in your video above. Unfortunately, both buttons are stuck down with corrosion, so I can't get underneath them with a flathead screwdriver to remove them like you have suggested. Luckily the toilet can still be flushed by pushing down because the buttons are not flush-no pun intended-with the tank lid the whole flush valve can depressed by pushing the buttons down. I'd like replace these buttons so I can have both the half and full flush available. Have you got any suggestions regarding the best way to remove them?
