Automating the Keyboard Maestro Editor with AppleScript

Is there an update for this for Keyboard Maestro 9? I recently upgraded and this broke. It looks like it is a long press on the back carrot or long press on the command button and I'm not quite getting this to work.

tell application "System Events"
  
  tell application process "Keyboard Maestro"
    set frontmost to true
    
    tell window "Keyboard Maestro Editor"
      tell group 3
        tell button 1
          perform action "AXShowMenu" -- Open Recently Run Macros Menu
        end tell
      end tell
    end tell
  end tell
  
end tell

From what I can tell using UI Browser it should be group 4 now and button 1 for the Used (command) icon.
