The plugin seems to save cookies in this format:
[domain] / [true or false] / [true or false] / [Epoch date/time] / [name] / [content]
Not sure what the true or false is, but you basically need to parse those lines and map them to your own
Entry struct (as theirs is not exported) - you might be able to use a CSV parser with a custom delimiter, then serialize it to JSON, then use the JSON you created to pass to Juju.
