I guess my question was a bit vague. How about, at the distance the telescope could detect exoplanets, what they would find out about our solar system?

If a alien civilization, say 10 to 50 million light years away developed a JWST and pointed it at our solar system. What and how much information they would they discover about us? I ask this because the JWST is promising to find exoplanets and their composition. I was wondering what it would look like from the opposite side to hopefully understand better on how the telescope works. (this is hypothetical, so imagine the the civilization is 10 to 50 million years in the future and looking at present day)
