B2 Cloud storage

I use b2 cloud storage and ui for php filament.

here is my b2 disk in filesystem

 'b2' => [
            'driver' => 's3',
            'key' => env('B2_KEY_ID'),
            'secret' => env('B2_APPLICATION_KEY'),
            'region' => env('B2_REGION'),
            'bucket' => env('B2_BUCKET_NAME'),
            'endpoint' => env('B2_ENDPOINT'),
            'use_path_style_endpoint' => true,
            'visibility' => 'private',
            'throw' => true,
            'checksum' => false,
            'options' => [
                'http' => [
                    'verify' => false,
                    'headers' => [
                        'x-amz-checksum-crc32' => null,
                    ],
                ],
            ],
        ],

```

here is my phpFilament code

```
 public static function form(Form $form): Form
    {
        return $form
            ->schema([
                Forms\Components\Fieldset::make("Profile")
                    ->schema([
                        FileUpload::make("file_name")
                            ->disk('b2')
                            ->visibility('private')
                            ->directory('images/actors')
                            ->preserveFilenames()
                            ->nullable()
                            ->label(''),
                    ]),

                Forms\Components\TextInput::make('name')
                    ->required()
                    ->maxLength(255),
            ]);
    }

it's work when I set FILESYSTEM_DISK=local in .env. But, it's not work when I change default disk as b2 in .env like this FILESYSTEM_DISK=b2. It's show 403. But I test upload with tinker, it's ok and this error happen in my webpage. how to solve this please.
