Tasmota Rule

Hi does anyone know how to configure a GPIO12 to 224 and setoption73 to 0 on Mqtt#Disconnected?
I tried the following based on what chatgpt gave me but it doesnt work. Also reading through the literature on Tasmota’s site was not fruitful. TIA!

Rule1 ON Mqtt#Disconnected DO gpio,12,224 ENDON
