Cannot see Zemismart 4 Button in HA

Configuration
1

I have integrated HA with Samsung smartthings (ST) where I added with success Zemismart 4 Button using the following script - https://github.com/YooSangBeom/SangBoyST/blob/7e01d36ba39171b1210d59a7bc1b7995aa44c66c/devicetypes/sangboy/zemismart-button.src/zemismart-button.groovy
In ST I can see the device with all 4 buttons and configure automation. Inside HA even when I reload the ST integration the Zemismart is not displayed.
Do you know what I could do to make it visible or how I can catch ST events inside HA?

Thank you

Found a solution based on creating a virtual switch inside ST. That is triggered by automation when I click the button. The virtual switch is visible inside HA.
