If anyone is coming across this post as I did trying to do the same thing, I found the following post with an updated smartapp that allows contact sensor state changes. Just tested it and it works great!
SmartThings-ESP32-Multi-Device
This project consists of code for an ESP32 to interface with SmartThings using the SmartThings MQTT Bridge. While any ESP32 can be used, ones with built-in displays like Heltec Wifi Kit 32, Wemos ESP32 LoLin and even the Heltec Wifi Kit 8 (ESP8266) should be considered instead. The project includes Samsung SmartThings Device Type handlers for a stateful (on/off) switch, a stateless/momentary button and a contact sensor. The project also supports a variety of temperature & humidity sensors which can be seen on all 3 device types. Two of each capabilities (switch/button/contact) can be ran on each ESP32 device.
