Identify if its possible to perform a zone transfer and submit the TXT record as the answer. (Format: HTB{...))

Hi. I’ve been stuck on this question of the Footprinting module for hours and I just do not understand what I’m supposed to do. Any help or hints would be greatly appreciated.
I’ve tried ‘dig axfr’ on all sorts of combinations but mostly get the ‘not found’ response.

Use man dig or dig --help to get some help with the dig command!

After you do the zone transfer, try using dig txt with some of the subdomains to query their TXT records.
