I did it on an old laptop running Ubuntu from a flash drive. I've made sure to take the internal wireless adapter away before proceeding. Before running the Electrum client, I've compared the hash of the executable file versus the one given by the site. It matched, so I went ahead and opened the application to create a new wallet address (native segwit/bech32) in an air-gapped environment.

I'll be sure to contact you via PM if I have any doubts about claiming forked coins. Thanks for the help, brother! I'm locking this thread now as my problem is solved.
