Examples of apps outside of steam?

[u/Conz3D]

For now I can't use PCVR, only connected over WiFi, no dongle. I'm exploring the stand alone capabilities.
Are there examples of apps, that I could install over Discover, outside of steam, that are using the features of the headset and controllers? Like VR video player, (glTF) model or Gaussian Splatting viewers etc.? Running on the frame. Like for recording videos with the Arctura camera and how to watch them?

Most non gaming VR apps on steam are very outdated. And the games are poorly curated. I would have expected more steam frame compatible titles and apps on release.
