You can also use Ian Coleman's tool... you just put the zpub into the "BIP32 root key" box at the top (leave everything else blank):
Then click the BIP141 tab, make sure derivation path is set to: m/0
and then select the "script semantics" for the address type that you want (should be P2WPKH as you have a zpub which is for native segwit, nested segwit would be a ypub, legacy would be xpub)
Then scroll down to see the derived addresses:
m/0/2 appears to be: bc1qgheaqg9xuetndfzpkk3tuphnleephr3g54rs9t
NOTE: when pasting long strings into bitcointalk, it will add extra "hidden" spaces... so you need to wrap them in [ code ] [ / code] tags to stop the forum software from doing this... like this:
