Toggle "Show scroll bars" radio buttons in Appearance section of System Settings via AppleScript

Question

I need to write AppleScript that sets some value to Show scroll bars in new System Settings UI.

Screenshot of what I want to change in result

Here's a code with which I did come up

tell application "System Settings"
    activate
    set current pane to pane id "com.apple.Appearance-Settings.extension"
end tell

delay 0.1

tell application "System Events" to tell application process "System Settings"
    -- ...
end tell

Answer 1

I found Accessibility Inspector application in which you can view the hierarchy of elements in any app. With its help, I wrote the working script:

tell application "System Settings"
    activate
    set current pane to pane id "com.apple.Appearance-Settings.extension"
end tell

delay 0.1

tell application "System Events" to tell application process "System Settings"
    set frontmost to true
    tell window 1
        tell group 1
            tell splitter group 1
                tell group 2
                    tell group 1
                        tell scroll area 1
                            tell group 2
                                tell radio group 1
                                    set targetUIElement to a reference to radio button 1
                                    if targetUIElement exists then
                                        click targetUIElement
                                    end if
                                end tell
                            end tell
                        end tell
                    end tell
                end tell
            end tell
        end tell
        tell button 1 to click
    end tell
end tell
