Hi everyone! I’m currently building a game on Sui where each playable character is represented as an object. I assume this should be modeled as an NFT, so I created a struct like this:

public struct Character has key, store {
    id: UID,
    owner: address,
    name: string::String,
    level: u64,
    experience: u64,
    health: u64,
    weapon: Option<Weapon>,
    armor: Option<Armor>,
    image_url: Url,
}

s there a standard or trait I need to implement for the Sui Explorer (or other NFT-compatible UIs) to recognize my object as an NFT? and Do I need to use or extend from the sui::nft module or implement certain fields (like name, description, url) in a specific way?
