Upload to Digital ocean spaces copies files to public folder

My method for uploading files to digital ocean spaces works perfectly but the files are uploaded both in project's public folder and spaces directory. I want to only upload files to digital ocean spaces and keep none in the project directory how can I go about this??

here is how my upload function looks like

if ($file = $request->hasFile('display_image')) {
            $post_image = $request->file('display_image');
            $filename = $post_image->getClientOriginalName();
            $compressed_image = $this->compressImage($post_image, $filename);
            $path = Storage::putFileAs('uploads/displayimage/'.$post->post_id, $compressed_image, 'public', 'spaces');
            $post->display_image = $filename;
        }

here is my file system configuration

'spaces' => [
            'driver' => 's3',
            'key' => env('SPACES_ACCESS_KEY_ID'),
            'secret' => env('SPACES_SECRET_ACCESS_KEY'),
            'region' => env('SPACES_DEFAULT_REGION'),
            'bucket' => env('SPACES_BUCKET'),
            'endpoint' => env('SPACES_ENDPOINT'),
            'url' => env('SPACES_URL'),
            'visibility' => 'public'
        ]
