Example is using an unknown variable

[TELUS-Alexander]

Hello,

In your example, you are using the $fields variable but it has not been initiated and there is no way to know what is being referred there.

https://github.com/filestack/filestack-php#storage

$metadata = $client->getMetaData($filelink->handle, $fields);

I noticed it while going through your documentation.

By default, does it retrieve all fields if the value is empty?
