How Do I "Unwrap Sol" Using the Web3 Sdk?

I need to unwrap some SOL using the web3 sdk. I'm wondering, Is it just a simple transfer from the wrapped account into SOL account or is it more complicated than that? Below Is just some sample code I've setup.

const emptyWSolAccount = async (amount:any) => {
  const wsolAddress = await Token.getAssociatedTokenAddress(
    ASSOCIATED_TOKEN_PROGRAM_ID,
    TOKEN_PROGRAM_ID,
    new PublicKey("So11111111111111111111111111111111111111112"),
    wallet.publicKey
  );

  const wsolAccount = await connection.getAccountInfo(wsolAddress);

  if (wsolAccount) {
    const transaction = new Transaction({
      feePayer: wallet.publicKey,
    });
    const instructions = [];

    const lamports = amount * LAMPORTS_PER_SOL;
    
    instructions.push(
      SystemProgram.transfer({
        fromPubkey: wsolAddress,
        toPubkey: wallet.publicKey,
        lamports: lamports, // 1 sol
      })
    );

    transaction.add(...instructions);
    transaction.recentBlockhash = await (
      await connection.getRecentBlockhash()
    ).blockhash;
    transaction.partialSign(wallet.payer);
    const result = await connection.sendTransaction(transaction, [
      wallet.payer,
    ]);
    console.log({ result });
    return { result };
  }

  return ;
};
