Need help wiring PGM to a zone to trigger alarm from homeassistant

Question

Hi I installed the PAI interface in HomeAssistant and everything works fine. This integration is impressive!!
I'm trying to trigger the alarm from assistant because I have additional Ubiquiti Sensors and Cameras.

I have 2 PGMs showing up (auto-discovered) and believe they don't do anything.

Apparently the solution would be to have a PGM trigger the alarm, but I have no clue as to what to do ;)
I found this comment from @yozik04, but I have no idea how to wire my zone to the PGM.

          Fully unsupported. Use PGM wired to a zone to trigger alarms.

Could you point me in the right direction?
I attached a photo of the Magellan...
I just bought this house with this alarm system and I don't know the installer pin-code (which is not 0000).

Logs (if required)

Wiring a 12V PGM to a Zone through 1kOhm resistor might work.
