Generate new "Hide My Email" email with iCloud+ using AppleScript

hideMyEmail.applescript

-- Kill System Preferences first if already open
if application "System Preferences" is running then
  tell application "System Events"
    set theID to unix id of processes whose name is "System Preferences"
    try
      do shell script "kill -9 " & theID
      delay 0.1
    end try
  end tell
end if

try
  tell application "System Preferences"
    activate
    set the current pane to pane id "com.apple.preferences.AppleIDPrefPane"
    tell application "System Events"
      repeat until window "Apple ID" of application process "System Preferences" exists
      end repeat
      set theWindow to window "Apple ID" of application process "System Preferences"
      
      -- Select iCloud
      repeat until row 6 of table 1 of scroll area 1 of theWindow exists
      end repeat
      select row 6 of table 1 of scroll area 1 of theWindow
      
      -- Right part of the window
      set rowDetails to group 1 of theWindow
      
      repeat until row 4 of table 1 of scroll area 1 of rowDetails
      end repeat
      
      -- Select the "Hide my Email" row
      set hideMyEmailRow to row 4 of table 1 of scroll area 1 of rowDetails
      
      repeat until button of UI element 1 of hideMyEmailRow exists
      end repeat
      
      click button of UI element 1 of hideMyEmailRow
      
      log "Clicked at: " & (value of static text 1 of UI element 1 of hideMyEmailRow)
      
      -- New opened window, which is a sheet
      set hideMyEmailSheet to sheet 1 of theWindow
      
      -- Wait for the busy indicator to appear
      repeat until busy indicator 1 of hideMyEmailSheet exists
      end repeat
      
      -- Then wait for it to disappear
      repeat until (not (busy indicator 1 of hideMyEmailSheet exists))
      end repeat
      
      set sheet1 to sheet 1 of theWindow
      set addButton to button 1 of group 3 of group 1 of group 1 of UI element 1 of scroll area 1 of sheet1
      click addButton
    end tell
    log "End"
  end tell
on error errMsg
  log "ERR: " & errMsg
end try

Seems to not work on macOS Monterey 12.6, failing on line 54:

Clicked at: Hide My Email
ERR: System Events got an error: Can’t get group 1 of UI element 1 of sheet 1 of window "Apple ID" of application process "System Preferences". Invalid index.

Is there an Xcode tool I can use to find the group / sheet / button numbers for a window?
If it's helpful, this is the window as it appears to me:

On my Mac (Monterey 12.6) the first group instance requires amending from "3" to "1"

Replace line 54...
set addButton to button 1 of group 3 of group 1 of group 1 of UI element 1 of scroll area 1 of sheet1

with the following line...
set addButton to button 1 of group 1 of group 1 of group 1 of UI element 1 of scroll area 1 of sheet1

@DeepHeat01 that did it, thanks!

Oops, I didn't see those notifications. Sorry!
I will maybe try to make something more like an app, since AppleScript isn't very practical for this usage. But Apple is limiting almost everything on this side unfortunately 👎
