None of the stars in the image of SMACS 0723 are bright enough to be shown in the picture you've provided of Volans.
SMACS 0723's at right ascension 07h 23m 19.5s, declination -73° 27′ 15.6”, and the image is approximately 2.4 arcminutes across, according to "Webb’s First Deep Field: Galaxy Cluster SMACS 0723" from constellationguide.com.
The view field of the SMACS 0723 image is too small, and the stars within it aren't bright enough to be among the stars that are in the image you've provided.
My version of Stellarium locates the object at a slightly different position, but with the brightness minimums set to magnitude 5.7, and field of view of 11.7° no stars in my attempt at approximation of your provided image are nearby enough to appear in the JWST image.
(My personal version of Stellarium doesn't show any stars at all close enough to the location to appear in the image even when I kick the brightness limits down to magnitude 12. I don't have enough information in my Stellarium install to definitively identify any of the potential stars in the JWST deep-field image.)
