How to set an ERC721 Token as a collectible within Trustwallet?

[alexacostarua]

I've gotten an ERC721 token contract created. I have the tokenURI, the token ID, the contract, the name, and symbol. I was wondering how do I set the variables :

@objc dynamic var id: String = ""
@objc dynamic var uniqueID: String = ""
@objc dynamic var contract: String = ""
@objc dynamic var name: String = ""
@objc dynamic var category: String = ""
@objc dynamic var annotation: String = ""
@objc dynamic var imagePath: String = ""
@objc dynamic var externalPath: String = ""

I know the id is the tokenID, the contract is the contract address, plus obviously the name, and imagepath. But how would I set the rest of the variables to make the token show up as a collectible?
Thanks.
