How to set System Preferences-> Display -> Scaled -> More Space with the help of AppleScript?

I got till:

```
    tell application "System Events"
        tell process "System Preferences"
            set frontmost to true
            click button "Displays" of scroll area 1 of window "System Preferences"
            click radio button "Scaled" of radio group 1 of tab group 1 of window "Built-in Retina Display"

```

But not sure how to set the " More Space" option?

TIA
