Trying to install a smart switch

Trying to install a tapo smart switch

First time home buyer. Bought a smart switch to replace traditional switch in wall. The instructional video mentions to label 1. White wire as Neutral 2. Green/bare copper as neutral 3. Red/black as live load

I opener up my wall plug but it seems two wall switches are connected with each other.

Please guide me in how to best go about it , or is this something i should hire an electrician to complete?
