创建token + bnb对后如何查找LP token的地址？

我使用 BSC 主网的分叉

hardhat.config.js：

require("@nomicfoundation/hardhat-toolbox");
require("@nomicfoundation/hardhat-chai-matchers");

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  solidity: "0.8.9",
  networks: {
    hardhat: {
      loggingEnabled: false,
      allowUnlimitedContractSize: true,
      forking: {
        url: "https://bsc-dataseed.binance.org",
        chainId: 56,          
      }
    }
  }
};

测试.js文件：

const [ deployer ] = await ethers.getSigners();
const pancakeSwapAddr = "0x10ED43C718714eb63d5aA57B78B54704E256024E";

const myTokenFactory = await ethers.getContractFactory("MyToken");
const myToken = await myTokenFactory.deploy();
const myTokenAddr = myToken.address;

const pancakeSwap = await hre.ethers.getContractAt("IPancakeRouter", pancakeSwapAddr);

let amount = ethers.BigNumber.from(1000000000000000000);
await myToken.mint(deployer.address, amount);
await myToken.approve(pancakeSwap.address, amount);

let zeroAmount = ethers.BigNumber.from(0);
let date = (await provider.getBlock("latest")).timestamp;
let fiveMinutes = ethers.BigNumber.from(5).mul(60);
let deadline = ethers.BigNumber.from(date).add(fiveMinutes);

await pancakeSwap.addLiquidityETH(myTokenAddr, amount, zeroAmount, zeroAmount, deployer.address, deadline, { value: amount });

调用后如何获取 LP 令牌地址添加流动性ETH功能？
