How to connect a four-way switch to SmartThings Station?

Hello everyone, I recently designed a four-way switch to connect to SmartThings Station and encountered many difficulties.

  1. I read some developer documentation (Get Started With Hub Connected Devices | Developer Documentation | SmartThings), but some links cannot be opened, as shown in the image.

  1. I downloaded the smartthings-cli tool (smartthings-win-x64, Releases · SmartThingsCommunity/smartthings-cli · GitHub) from GitHub, but it crashes, preventing me from proceeding. I hope to get your help, thank you
