AVContentKeySession API equivalent on MacOS/Safari?

Question

I am implementing a Fairplay Streaming player on Safari.It needs to prefetch a set of keys from KSM before the playback. All the examples I came across implement AvContentKeySession api but it is available only in Swift and Objective-C(for ios). What is equivalent of AVContentKeySession API on MacOS/Safari? Is there a reference code available to implement such a functionality on MacOS/Safari?
