“terminal-notifier.app” cannot be opened because the developer cannot be verified

When I update os from Big Sur to Monterey and open terminal-notifier.app it shows me the message

“terminal-notifier.app” cannot be opened because the developer cannot be verified.

Why it shows me the messages


  • Navigate to the application in Finder
  • Right-click it and select "Open"
  • Confirm in the dialog which will be shown

It should work as before from now on.
