Hi, I am trying to implement the friends section of the Platform SDK but I am having trouble finding documentation on it. I have been looking at https://developer.oculus.com/documentation/platform/latest/ and the Oculus Platform Reference Manual but sections seem to be not covered in them and/or no information is given on elements. Can someone please point me in the direction of more detailed documentation on the Oculus Platform or are these 2 currently the only available?
