images not showing using spatie media library in filamentphp

I am having trouble displaying the images uploaded using spatie media library with the filament admin panel.

image for clarificatio

This is the code for form schema :

SpatieMediaLibraryFileUpload::make('thumbnail')->collection('posts')

And this is the code for table columns

SpatieMediaLibraryImageColumn::make('thumbnail')->collection('posts')

Thanks.
