Shelly 1 - Change voice command in SIRI for opening garage door

hello everyone,

Is somebody out there who manage to change the voice command in Siri for opening a garage door?
At that time the Shelly 1 interacts for open and close the garage door ( set it as a button) only with
“hey Siri turn on Garage door”
Is any other way or have to make a custom firmware somehow?
thank you all!
