Probably it's SDSS J234356.99-030230.7 ((α, δ) = (23 43 57, -03 02 31)).
Interesting: The image below shows that a survey of Jupiter was previously made with Hubble at almost the same position. The fact that Jupiter (HST) appears about 6 times too large compared to the image of Neptune (JWST) is due to the difference in the spatial positions of the planets and the telescopes at different times.

AVAO, I'm not sure I understand what you mean by Jupiter being 6 times too large compared with Neptune in the HST image compared with the JWST image. Isn't Neptune almost 6 times farther away than Jupiter, and doesn't that have to make it look much smaller?
You're right with your question. True, the Lagrange point is much further away than Hubble's location. But still almost negligible compared to the distance to Neptune. If the JWST were to depict a future conjunction of Neptune and Jupiter, the proportions would probably be similar to my image with superposition. (But the size comparison in the second picture is insofar meaningless.)
