How can I make my form action show a confirmation modal?

public function form(Form $form): Form
    {
        return $form
            ->schema([
...
                Actions::make([
                    Action::make('delete')
                        ->requiresConfirmation() // This doesn't make a modal show
                        ->action(function () {
                            $this->doDelete($this->item->id);
                        })
                ]),
        ]);
    }
