Hubitat + HomeKit + SecurityPanel

Looking to get help in writing a custom driver. i added the line capability 'SecurityKeypad' to my custom driver and have the neccessary armStay() armAway() functions but HomeKit Doesnt see the Security System. It correctly sees and lists all the Sensors however. What is the keyword i need to add to driver file so HomeKit Recognizes this device as capable for Arm Home, Arm Stay & Disarm. I know this is doable because in homebridge there is a plugin that does just that but i dont understand TS just yet.

GitHub - schwark/hubitatADC: Hubitat App and Driver uses three switches named "Disarm", "Arm Stay", and "Arm Away". If you don't find what you are looking for, that might be a viable alternative.
