I have something vaguely similar and there’s probably more than one way to do this, but usually you have an automation which has a trigger, condition and action;
However the action can be split out into different things. My morning announcement is automation → scene → script
Here’s a bit more detail;
Edit: I don’t have a Google Home, but I’m guessing you’d probably call a scene from Google Home, I don’t think you’d be able to activate by a specific command. So you wouldn’t necessarily need an automation, just a scene which does all this and then you could say “OK Google, turn on Leaving for Work”
