Cloud XR 4.0 does not support Vive Focus 3?

Hey … in the new Cloud XR 4.0 folder is no longer a sample app for Vive Focus 3 … only for Occulus.
Are HTC devices no longer supported?

CloudXR provides libraries to enable partners like HTC to build clients & developer samples that perform best on current and future devices. HTC has provided samples that use the CloudXR libraries since 3.0 and we anticipate a continuation of this for version 4.0.
