How to replace a touch button (capacitive) with dry contacts?

Question

Circuit design

Actually here is the question.
on the board we have a spring sensor, it works through the glass on the front panel, you need to remove the contacts parallel to this button from the device.

Answer 1

Connect an opto-transistor after the capacitive button driver and output it already. It is not necessary to output directly from the device - only through galvanic isolation.

Answer 2

the buttons are reduced to the WTC6208 chip, I can’t find a datasheet on it
