Putting my virgin go app onto kodi

Hi, All wondered if anyone can help.
I have been trying this morning to get my virgin tv go to work on my amazon firestick! Obviously no luck so far.
Came across kodi and from what i have been reading using kodi with my virgin go app on it should work, but i have no idea how to get it working.
Anyone know how? 
Just to be clear, i have no interest is illigal stuff all i want to do is access my virgin go app.
Has anyone got a solution to this.

Thank you for any replies.
