Yeah, just paste that code in their website and wait about an hour to update.

Ok so it confirmed the new username I chose worked with the hex you provided, and when I pasted the new username in my Amethyst it automatically updated in the Primal client and shows the check in primal but still won't in Amethyst.. I will give it a little time but it worked immediately in the primal client..
Frankly, I don't know what primal is doing. There is no THEDISTRICT registered in the site yet (it is still updating).
Lol all good, I just thought it was odd that when I updated my NIP-05 I'm Amethyst that it updated it Primal as well without going to the Primal client, which to me says we are using the correct npub but I'm no web3 dev..
You can see the list of all usernames they have here: https://nostraddress.com/.well-known/nostr.json?name=THEDISTRICT
or here if you are using the "verified" domain:
https://nostrverified.com/.well-known/nostr.json?name=THEDISTRICT
This also just showed a extremely large string of black and white code
Woahhh that just brought up a bunch of black and white code 😅😬
