How to turn VersionedTransaction with Address Lookup Tables into VersionedTransaction without Address Lookup Tables

Question

I have a versioned transaction with an address lookup table. However, I need to convert it to one without an address lookup table (that is, the addresses will contribute to the 1232 byte limit per transaction). How would I go about doing this?

Preferred language: Typescript then Python if necessary

I think you can just grab the instructions and create a new transaction with them

const V0MessageWithLUT = .... // update with your transaction

let instructions = TransactionMessage.decompile(V0TxWithLUT).instructions;

const messageV0 = new TransactionMessage({
    payerKey: me.publicKey,
    recentBlockhash: (await connection.getLatestBlockhash()).blockhash,
    instructions: [...instructions],
}).compileToV0Message();

let tx = new VersionedTransaction(messageV0);
