如何通过 web3 获取钱包地址中可用的合约的 nft 代币

Question

I have a NFTs-Contract address on ethereum. I want to know a wallet address have which token of my contract. How can I get list of tokenId which are in a wallet address by web3?

const Web3 = require("web3");const provider = "https://lively-withered-grass.quiknode.pro"
const Web3Client = new Web3(new Web3.providers.HttpProvider(provider));
const minABI = [
    {
        constant: true,
        inputs: [{name: "_owner", type: "address"}],
        name: "balanceOf",
        outputs: [{name: "balance", type: "uint256"}],
        type: "function",
    },
];
const tokenAddress = "0x0d8775f648430679a709e98d2b0cb6250d2887ef";
const walletAddress = "0x1cf56Fd8e1567f8d663e54050d7e44643aF970Ce";
const contract = new Web3Client.eth.Contract(minABI, tokenAddress);
async function getBalance() {
    const result = await contract.methods.balanceOf(walletAddress).call();
    const format = Web3Client.utils.fromWei(result); // 29803630.997051883414242659
    console.log(format);
}
getBalance();

I am able to know that in a wallet address whether or not any my token but it doesn't give me any information about which token are existed in wallet.

Do you have any solution?
