lists

Good morning. I use wordpres with wocommerce installed. the user who purchases within my ecommerce completes all the fields related to registration.
however, I would like to add a field where the user also indicates his specialty as a doctor.
for example anesthesiologist rather than orthopedic. So far, no problem, but what I can’t do is then retrieve the lists of all anesthetist or orthopedic users. is there a plugin? Thanks so much
