In extension workflow - some envs not updating in viewport

[VladimirFokow]

In the extension workflow, in video example here (at 1:34),
after we click "START" we can see the cartpoles moving in the viewport.

When I try the same with Humanoid - it doesn't move (nor if "Test" is selected)
In the terminal I see that it is training -- but it just doesn't render in the viewport.

If I launch the training from the command line (not with the extension) (with headless=False by default), a window opens and there everything DOES move.

If I create my custom env, will I be able to check its training progress with the extension workflow? - how to ensure that it will be moving?

Envs:

This is caused by OmniHydra instancing not being enabled when we are using extension workflow. I believe all robots that don't move are using instanceable assets. I did see a warning in the command prompt, but currently I don't know how to enable it.
