AppleScript for locking the screen in Catalina Is there a way to build an AppleScript for locking the screen? I want to add a Quick Action (and the relative button on the Touch Bar as described here)

This solution i.e.,

tell application "System Events" to tell process "SystemUIServer"
    tell (menu bar item 1 of menu bar 1 where description is "Keychain menu extra")
        click
        click menu item "Lock Screen" of menu 1
    end tell
end tell


does not work in Catalina. After allowing accessibility for Apple Script Editor from Security and privacy, I still get this error in automator:


  Can’t get menu 1 of menu bar item 2 of menu bar 1 of application
  process "SystemUIServer". Invalid index.
You can use:

tell application "System Events" to keystroke "q" using {control down, command down}


You could also use the following instead:

tell application "System Events"
    set appName to (name of every application process whose frontmost is true and visible is true) as string
    click menu item "Lock Screen" of menu 1 of menu bar item "Apple" of menu bar 1 of application process appName
end tell

However, the first mentioned solution is more direct.
