sadly i wanted to have an answer for you but i dont... in fact i just heard of it right now... so i added some information to help you guys up if you are willing to put up the work....
i have pulled the Official SDK and Documentation from the official GitHub Repository for those who are interested into building the plugin... but not sure if it will work.. since im guessing will check if its compiled using Unity Engine... but if you guys can work around that ... wold be great to have it shows potential ...
