How to use funscripts with a Kiiroo Keon on Play'a for Android (Cardboard)?

I understand that Cardboard is not the ideal scenario, but that’s the only device I have available. I have the mp4 videos and the funscript files for my videos. How can I use my keon with Play’a on Android?

I also have a Macbook in addition which I can use as a server etc if required.
