[How to stream a Three.js app from PC to Focus 3? SteamVR Home keep booting up instead!]

SteamVR Home boots up when we stream WebVR/WebXR on Firefox on PC. For instance, if we open Mozilla Hello WebXR on Firefox, SteamVR boots SteamVR Home on the headset. We are developing a GPU-demanding Three.js app that we cannot stream to the Focus headset because of the mentioned behavior.

How can we resolve this issue? Due to the GPU demand, hosting the app online and rendering it on the headset is not an option.

[Steam Home starts instead of streaming WebVR content from Firefox]

When I stream WebVR/WebXR content from Firefox on Windows, SteamVR opens Steam Home instead! I have tested several demos on https://mixedreality.mozilla.org/, and this behavior is persistent. I picked up developping VR with Three.js, so I want to be able to stream VR content from Mozilla Firefox on my workstation.

How can I fix this?
