Why don’t we constantly see new stars in the sky as an increase of light travels to us?

Question

with how light works and the constant expansion of what we term the “observable universe” why don’t we constantly see new stars appearing in the night sky as the observable part expands and stars/galaxies light reaches us for the first time?

The night sky has stayed relatively the same (accounting for changing postions over time, stella phenom, supernovas etc.) for all of humans written history.

Answer 1

Our galaxy is 105,700 light years across. We can “see” the entire width from earth already. Stars in other galaxies are too dim to see with the naked eye.

Using telescopes, we can already see loads of other galaxies as well. But the distance between galaxies is often another 100,000 light years (or more!). So new ones aren’t “added” to our field of vision very often.
