I have recently began using Home Assistant to bring in all my smart gadgets into one place but my 10 year old HKC alarm is very dumb

Has anyone here been able to successfully integrate it with Home Assistant so it can be controlled from there?
I have asked an engineer to see what options I have and for my current model I can only add the GSM module no LAN/wifi cards available. Or go for the 1070 panel and I can use Wifi and the HKC app (with a monthly fee of course) to control it - this would give me remote control capability but did not find a way to integrate it with Home Assistant
