How to configure the Enterprise Tyk Developer Portal to render API documentation in English and Arabic

Hi,
How can I configure the Enterprise Tyk Developer Portal to include API documentation (including specs and user guides) in English and Arabic?
On the live portal, the default language setting will be English. A customised theme will provision a language toggle from English to Arabic. If the developer selects Arabic, then they should be able to view the API specs and getting started user guides in Arabic.
In the API Product page, I can upload only one API spec file per API. Does this mean I should maintain different versions of the API for bi-lingual specs?
Any advice on how to implement this is welcome.
Thanks and Regards.
