Converter won’t work

Hello,

I’ve set up a custom uploads folder using the following script

add_filter( 'webpc_htaccess_rewrite_path', function( $prefix ) {
    return '/';
} );
add_filter( 'webpc_dir_name', function( $path, $directory ) {
    switch ( $directory ) {
        case 'uploads':
            return 'website.gr/custom-folder';
    }
    return $path;
}, 10, 2 );

When I’m using the plugin it would swap the original images for webps only for images in the /uploads/ folder, ignoring the custom setting

Is there something I can do to get the plugin working properly?

Thanks in advance
