Retrieve all wallet addresses from public key

I’m trying to get an account balance from a seed phrase.

I’m first retrieving the public key from the seed const { publicKey, /*privateKey*/ } = parseSeedPhrase(seedPhrase);.

And then I’d like to retrieve all the account addresses associated to that public key, whether it’s a named account or an implicit account. I’m try with the following: const address = nearAPI.utils.PublicKey.fromString(publicKey).data.hexSlice(); but it only returns one address.

Here is the full code:

const nearAPI = require("near-api-js");
const { parseSeedPhrase } = require('near-seed-phrase');
require('dotenv').config();

const seedPhrase = process.env.SEED_PHRASE;
console.log(seedPhrase);

// To recover keys from the seed phrase
const { publicKey, /*privateKey*/ } = parseSeedPhrase(seedPhrase);
console.log(publicKey);

// To recover address from the public key
const address = nearAPI.utils.PublicKey.fromString(publicKey).data.hexSlice();
console.log(address);

const { connect } = nearAPI;

const connectionConfig = {
  networkId: "mainnet",
  nodeUrl: "https://rpc.mainnet.near.org",
  walletUrl: "https://wallet.mainnet.near.org",
  helperUrl: "https://helper.mainnet.near.org",
  explorerUrl: "https://explorer.mainnet.near.org",
};

// gets account balance
const getBalance = async() => {
  try {
    const nearConnection = await connect(connectionConfig);
    const account = await nearConnection.account(address);
    const balance = await account.getAccountBalance();

    if (parseFloat(balance.total) > 0) {
      console.log(balance);
    };
  } catch (e) {
    console.log(e);
  }
}

getBalance();
