Ember call action in application route with return value

In Ember you can call an action in your current context as you would a normal function, using this.actions.actionName(). This means the action can return a value.

In my login route, I am trying to call an action from the application route in this way. However this.actions only contains the actions in my login route.

Login Route

actions: {
  test: function() {
    console.log(this.actions.sameRouteAction()); //5
    console.log(this.actions.applicationRouteAction()); // this.actions.applicationRouteAction() is not a function.
  },
  
  sameRouteAction: function() {
    return 5;
  }
}

Application Route

actions: {
  applicationRouteAction: function() {
    return 7;
  }
}

What would this.actions.applicationRouteAction() have to become in order for this to work?
