How to generate a Litecoin testnet addresses (Segwit also) (Derivation path, bip32) I'm creating a wallet that generates address for litecoin mainnet in two ways.

One is using bitcoinjs-lib. This library has an object with all the data need it to create private keys and address:

import Bitcoin from 'bitcoinjs-lib'

console.log(Bitcoin.networks.litecoin)
{
    messagePrefix: '\x18Bitcoin Signed Message:\n',
    bip32: {
        public: 71979618,
        private: 71978536
    },
    pubKeyHash: 111,
    scriptHash: 196,
    wif: 239
}


This ok for the mainnet, but I am not able to find on internet the same version of this for testnet.

The other way is using derivation paths. But again, I only could find the mainnet version of this.

mainnet: `m/44'/2'/0'/0/${index}`
mainnet_segwit: `m/49'/2'/0'/0/${index}`


Any idea where I can find it?
const ltcnet = {
    messagePrefix: '\x19Litecoin Signed Message:\n',
    bip32: { 
      public: 0x043587cf,
      private: 0x04358394
    },
    pubKeyHash: 0x6f,
    scriptHash: 0xc4, //  for segwit (start with 2)
    wif: 0xef
  }


use it like this: 

var key = bitcoin.HDNode.fromSeedHex(seed, ltcnet)
