As the title suggests I need help with changing the URL of a wiki I made which is the technoblade Wiki

So at first when I created it, it was in use the https://technoblade.fandom.com

URL as it was being used by another Wiki but the wiki using it is closed but I didn't really care but still would have wanted the URL to be https://technoblade.fandom.com but today I checked if there is any duplicates and now apparently it's not in use anymore so I'm trying to figure out how to change the url from https://technoblademc.fandom.com to https://technoblade.fandom.com

Does anyone know how to change urls
