How do I access the uploaded file?

public function form(Form $form): Form
    {
        return $form->schema([
           
         
            FileUpload::make('document')
                ->label('Upload Document')
                ->preserveFilenames()
                ->acceptedFileTypes(['application/pdf'])
                ->maxSize(12288)
                ->storeFiles(false)
            //->hidden(fn () => $this->statement?->document_id !== null)
        ])->statePath('data');
    }

    public function save(): void
    {
        dd($this->form->getState());
}
