Example of using FairPlay on TVJS player?

Hello,

I've been digging for days and just can't find any example for playing FairPlay contents on TVJS player.

I have found loadKey, loadCertificate, and loadAssetId three attributes at the MediaItem class, but I just can't figure out how to use it correctly

(i.g. I can't get anything from the requestData of loadKey)

(ref: https://developer.apple.com/library/tvos/documentation/TVMLJS/Reference/TVJSMediaItem_Ref/index.html)

Is there any more details on this?

Thanks!
