This macOS app lets you promplty shutdown you mac.
For the first launch, right-click the Shutdown app and select 'open' and then 'open' again. Then, simply click on the app icon. Shutdown shall close automatically. For the first time opening, you need to allow Shutdown to access 'system events' under 'Automation' under the privacy section in Settings.
