segregated witness – The right way to create a litecoin testnet segwit pockets offline

Hello So I’m utilizing the bitcoinjs-lib pacakge to generate pockets handle and personal keys domestically nevertheless it looks like it is creating the litecoin handle of legacy kind, my objective is right here to create of segwit kind which has a prefix like tltc

right here is my code:

const bitcoin = require('bitcoinjs-lib');

perform generateLtcAddress() 
    const litecoinTestnet = 
        messagePrefix: 'x19Litecoin Signed Message:n',
        bip32: 
            public: 0x043587cf,
            non-public: 0x04358394
        ,
        pubKeyHash: 0x6f,
        scriptHash: 0xc4, //  for segwit (begin with 2)
        wif: 0xef
    ;

    const keyPair = bitcoin.ECPair.makeRandom( community: litecoinTestnet );
    const  handle  = bitcoin.funds.p2pkh(
        pubkey: keyPair.publicKey,
        community: litecoinTestnet
    );

    const privateKeyWIF = keyPair.toWIF();

    console.log("Litecoin Testnet Handle:", handle);
    console.log("Personal Key (WIF):", privateKeyWIF);
    return 
        handle: handle,
        privateKey: privateKeyWIF
    ;

Output:

Litecoin Testnet Handle: mnUDkLibVp1MhKSm6pvYgT26PUxeTjHJiR
Personal Key (WIF): cQgM1FZSkJWJ3eFs4xfYozfCt37KYKr1rEGEYwuNdquwsfzjASnM
