How can I start a Nearby Interaction with an Apple Watch?

I am excited to begin writing apps using Nearby Interaction between iPhones and the Apple Watch, and I see that the Apple Watch Series 6 includes the U1 chip, but there doesn't seem to be any Watch OS support.

I don't expect the full Nearby Interaction Framework to be available on Watch OS, but it at least needs to be able to generate a discoveryToken so that the iPhone app can detect it. Am I missing a way to do this, or is this reserved for a future Watch OS version?

Thanks,

Chris
Nearby Interaction API supports interaction between two or more iPhones only.

The Nearby Interaction framework streams distance and direction between opted-in Apple devices containing the U1 chip
Not necessarily, it says "apple devices with u1 chip", next apple watches have u1 chip
