Bitcoinjs-lib: version 4.0.1, Derive addresses from xpubkey

[larafale]

Hello guys, help much appreciated.

I use to be able to derive addresses from xpub keys like this (version 3.x.x) (note that the xpubkey I'm using is not segwit)

bjs.HDNode.fromBase58(xpub, network).neutered()
    .derive(0)
    .derive(0)
    .getAddress()

I've upgraded to 4.0.1 and it does not work anymore. I've tried

bjs.bip32.fromBase58(xpub, network)
    .derive(0)
    .derive(0)
    .getAddress()

but I get _bitcoinjsLib.bip32.fromBase58(...).derive(...).derive(...).getAddress is not a function"

also tried

const pubkey = bjs.bip32.fromBase58(xpub, network)
    .derive(0)
    .derive(0)
    .getPublicKeyBuffer()

const { address } = bjs.payments.p2sh({
  redeem: bjs.payments.p2wpk({
    pubkey: pubKey
  })
})

but I get _bitcoinjsLib.bip32.fromBase58(...).derive(...).derive(...).getPublicKeyBuffer is not a function

Anyone care to explain ? thank you very much

ok I've firgured it out:

const pubkey = bip32.fromBase58(xpub, network)
        .derive(0)
        .derive(0)

      return bjs.payments.p2pkh({ pubkey: pubkey.publicKey, network }).address
