I’m not sure if I am following your question, so I’ll try to answer it the best I can.
The voice commands for integrating Rule Machine and Alexa are the same commands you would normally use with SmartThings. So if I had a Rule to make my lamp Red I would create a virtual switch in ST, create a Rule that changes my lamp color when the virtual switch or button is pressed. I would then say “Alexa, turn on SWITCH NAME” or “SWITCH NAME On”. You can do this for any Rule. With this you can control Routines, Lights, Modes, etc.
“Alexa, Turn on RED MODE"
"ALARM INDICATOR on”
