Well, unless you are a moderator then you can't really see the database (I don't think), but whenever you come across players, your device automatically downloads the files. So in a sense, your phone already holds the database, unless they changed it.
There is a website that has a database with bodies and heads, though: https://www.graaldepot.com/customize
Not too sure if they're up-to-date but they have a massive collection to go through.
