I tried it out a bit more and it seems like the interaction profile is only available for the Android platform (which is why I didnt find it initially). Are there any plans for supporting the interaction profile of the Focus 3 with the Windows platform? That way, the Focus 3 would be useable for desktop OpenXR applications through VIVE Business Streaming and SteamVR's OpenXR runtime.
I've been able to get tracking and display to work with the Focus 3 in that context, but it is lacking input support since there is no interaction profile for that platform
