Language field is not used in LinkData

[alex-finnigan-mando]

I'm trying to use the LinkData type to create multilingual links. I can see that there is a language dropdown which is populated by the enabled languages in the CMS.

However, I can't find a way to get the value of this field in the code so I can apply it to the URL. It also doesn't appear to do anything to the Href field.

Do you know how this field value can be obtained or if not, how can I hide it and add a custom one?
