Dispatching an event from an Action

Hi, should i dispatch an event from an action like this?

Action::make('prova')
  ->action(function () {
      $this->dispatch('prova', ['prova']);
  })

Action::make('prova')
  ->action(function () {
      $this->dispatch('prova', ['prova']);
  })

Action::make('prova')
  ->action(function () {
      $this->dispatch('prova', ['prova']);
  })

Action::make('prova')
  ->action(function () {
      $this->dispatch('prova', ['prova']);
  })

->dispatch('prova', ['prova']) doesn't work
