The reason we need JWST instead of Hubble telescope to see extremely far objects is the reason why your statement is wrong

If the distant objects were expanding away from us faster than the speed of light then we wouldnt be able to observe them.

But we are able to observe them, because JWST is able to picture objects which wavelengths have been stretched into the infrared wavelengths, making it unobservable to Hubble, which can mostly detect visible light and some UV light.

We cannot observe things that are expanding away from us faster than the speed of light.
We can only observe the past of objects that are currently expanding away from us faster than light, because the evidence of that past was emitted before the object was expanding away faster than light.
That is the light that is highly red-shifted.

That's exactly true! That's called the observable universe, which is smaller than the actual universe. Our observable universe is expanding at the speed of light, but objects already outside of that bubble will NEVER be inside that bubble. They are forever outside our observable universe.
